Andy Burnham criticised people posting videos of themselves driving recklessly on social media as a teenager who died alongside four of his friends in a head-on crash on an Irish motorway was laid to rest today. Jeremy O'Brien, 18, became the fourth of the five joyriders to be buried during a funeral mass in County Carlow. Police set up several checkpoints around Carlow Town before the service and stationed a public order unit nearby over fears of possible disorder. Mr O'Brien died alongside Jack Kennedy, 17, Kamil Pustkowski, 17, Alex McCarthy, 17, and Joe Carthy, 15, when their car collided with another vehicle while driving against traffic on the M9 in County Kildare on August 16. At least three of the teenagers had boasted online about driving the wrong way down motorways to evade police. The car they collided into contained three sisters and a seven-year-old boy who are in hospital being treated for serious injuries. The horror was followed by the deaths of five more young men and two police officers on the A66 in Middlesbrough early on Saturday morning.PC Matthew Blades, 37, and PC Tom Clough, 38, were in an marked armed response vehicle near Teesside that was struck by a VW Passat containing Michael Robert Cahill, 23, Jacob Matusiak, 23, Makai Saddington, 18, Theo Rae, 17, and Cole Robert Worthy, 17.Another police car had been pursuing them before calling off the chase. Just ten seconds later, the VW struck Mr Blades and Mr Clough, who had not been involved in the pursuit.With 12 people killed in the space of a week, calls are growing for a crackdown on reckless drivers filming themselves performing dangerous stunts for social media likes.Videos of young people joyriding in stolen cars or inhaling laughing gas behind the wheel are becoming ever more prevalent across TikTok and Snapchat.The PM addressed the issue today during a visit to Kyiv, telling reporters that sharing footage glorifying dangerous driving was 'truly reprehensible'. Jeremy O'Brien became the fourth of the five joyriders to be laid to rest in a funeral in Carlow Town Police set up several checkpoints around The Holy Family Church prior to the service and stationed a public order unit nearby amid concerns over possible disorderJeremy O'Brien, 18, in a family photo Earlier, defence minister Luke Pollard said the Government has ordered social media companies to remove these videos from their platforms. He told BBC Radio 5 Live: 'We've communicated to those social media platforms that have been hosting content that celebrates this type of dangerous behaviour on our roads and urged them to take it down.'A Downing Street spokesman said Ofcom has the Government's 'full backing to take tough action' against platforms which fail in their legal duties.In Ireland this morning, a horse-drawn carriage arrived at The Holy Family Church in Askea – a suburb of Carlow Town – to carry the coffin following the funeral mass. Young men watched on wearing T-shirts with a picture of Mr O'Brien on the front.Father Tom Little told mourners there is a 'deep sense of sadness and loss'.'We pray for those who have been injured and mourn those who have died,' he said in his homily. 'The death of a young person is always difficult to accept.'There is something especially sad about a young life being taken suddenly, unexpectedly and before so many hopes and dreams have been realised.'Today our grief and sadness is made even heavier because this was an accident that affected not just one person alone.'Several lives have been lost and others have been seriously injured. Families have been changed forever.' Father Little asked mourners to think of the families of Ella Hendricken and Niamh and Alma Kinsella, who were left seriously injured after they were struck by the teenagers' car. A seven-year-old boy – a son of one of the sisters – was also badly injured. 'There are people in hospital fighting to recover, and there are families who are beginning the painful journey of learning to live with an empty place at their table,' he said. 'At times like this we are left with no words to express our sadness and loss. Today, we give thanks for the gift of life, however short it may have been.'Among those prayed for were the doctors and nurses caring for those who were injured in the accident, wishing them a 'full and speedy recovery'.The crash in Co Carlow brought into focus the 'Lucky Dip' gang of car thieves wreaking havoc in Ireland. Police believe the group, made up of around 60 members, steal cars for the thrill of joyriding and uploading footage to social media.But the vile trend is not confined to Ireland, with British road users also at risk from young drivers chasing online fame. A horse-drawn carriage arrived at the church to carry the coffin following the funeral mass Mourners at today's funeral at The Holy Family Church in Askea Father Tom Little told mourners that there is a 'deep sense of sadness and loss' Joe Carthy, 15, was another of the five teenagers who died in the car Kamil Pustkowski and Alex McCarthy were also in the car Ella Hendricken, Niamh Kinsella and Alma Kinsella all sustained catastrophic injuries after a crash on an Irish motorway that killed five teenage boys who had 'boasted about joyriding' Five teenage boys, all wearing balaclavas, were killed in the head-on collision as they drove south up the northbound carriageway on the M9 in County Kildare, IrelandBecky Guy, senior policy manager for the Royal Society for the Prevention of Accidents, said she was deeply concerned by the phenomenon of 'drivers appearing to take risks on the road for social media content'.'No amount of likes, views or online attention is worth the risk of death or severe injury,' she told the Daily Mail.'Decisions made in a matter of seconds can have serious consequences, not only for the driver and any passengers, but for other people using the road.'Nicholas Lyes, director of policy at road safety charity IAM RoadSmart, said young drivers appeared to feel 'invincible' behind the wheel and were brazenly flouting road safety rules by speeding and using their phones.'There has also been a growing trend in recent years of filming, sharing and uploading dangerous driving content, all of which is incredibly dangerous,' he added.There has been a spate of crashes involving reckless drivers that have resulted in deaths or serious injuries.Earlier this year, 21-year-old Liberty Mitchell was jailed for killing a taxi driver and his passenger after filming herself speeding on Snapchat.Footage showed her laughing with a filter on her face before turning the camera around to show the speedometer climbing.A second video caught Mitchell driving at 100mph on a 60mph country lane, while a third showed her veering onto the opposite side of a road towards an oncoming car as friends shouted for her to stop.Mitchell, who was 18 at the time of the crash, was travelling at 96mph when her Mini Cooper ploughed into three other cars. She was attempting to overtake three vehicles at once before aborting the dangerous manoeuvre and hitting a taxi.Taxi driver Octavian Codreanu was killed in the crash alongside schoolteacher Moyra Whelan, who was on her way to a wedding. Six others were also injured, three of them seriously.Nicola Cooper, a passenger in Mr Codreanu's taxi, said: 'The crash itself was traumatic. The impact felt endless. I live with survivor's guilt and the trauma of losing one of my closest friends, Moyra, who was sitting just inches from me.'I lie awake at night thinking about the "what-ifs".'

In a separate incident from this May, a drug dealer was jailed for three years and nine months for filming himself speeding at 119mph while serving a five-year driving ban.Extraordinary footage showed John Scott, 36, filming his speedometer climbing to 119mph as he accelerated along a single-carriageway country road while music played loudly in the background.Another video showed Scott singing, smoking and driving while wearing sunglasses and no top.Both clips were filmed while the criminal was partway through the five-year driving ban.'It is remarkable that no one was hurt,' PC Charlie Large, of Norfolk Constabulary, said.In a particularly horrific incident from 2023, then 17-year-old George Taylor filmed himself using his knees to steer his car shortly before he ploughed into a stationary vehicle.Catherine Davies, who was in a car waiting to turn at a junction, was left paralysed from the neck down. The single mother now relies on round-the-clock care in a specially adapted property fitted with life-support equipment.Taylor was later jailed for 26 months. George Taylor, aged 19 pictured outside court. The teenager filmed himself driving without his hands on the wheel and has now been jailed for 26 monthsDefence minister Luke Pollard said he wanted social media companies to 'step up'. This morning he said: 'I think we all need to give the police time, but there are also things we can be doing in the meantime to make sure that the internet is a safer place for everyone, one that does not reward dangerous behaviour with views and financial incentives.'I want to see social media companies step up. It's one of the reasons they've argued against some of the regulations, saying they can police themselves. Well, this is the perfect opportunity to demonstrate it. Remove the content that celebrates dangerous behaviour on our roads.'While that content is online, the Government will be using the powers in the Online Safety Act to compel platforms to take it down.'But if social media platforms were to regulate themselves and remove it in the first place, rather than allowing their algorithms to amplify it, then I think we'd be in a better place.'Videos are often shared anonymously on social media to avoid attracting police attention.On Instagram, one motorcyclist posts montages of stunts and 200mph sprints on public roads.A video from March shows the rider swerving across all three motorway lanes and is captioned: 'If I die, just know I sounded like this.' It attracted more than 155,000 likes.In Ireland, regulators are now considering hitting TikTok with fines of up to €1.53billion (£1.31billion) if it fails to clamp down on the videos.TikTok said it is closely monitoring content posted in relation to the M9 crash and is removing videos that breach its rules.Connor Charlton, a semi-professional footballer who plays for Nostell Miners Welfare in the Northern Counties East League, was caught speeding over 100mph on multiple occasions Drug dealer John Scott has been jailed after he filmed himself speeding at 119mph while disqualified from drivingThe company said it removes content that glorifies violence or promotes criminal activity.Cleveland Police and Crime Commissioner Matt Storey called the social media trend 'absolutely idiotic'.Asked this morning about Saturday's tragedy in Teesside, he told Radio 4's Today programme: 'Without being able to say whether that was in any way involved in this case, it's absolutely idiotic for anybody to be doing anything other than being completely focused on the road when they're behind the wheel of a vehicle.'For somebody to be filming themselves, or doing anything like that, is absolutely ridiculous and, of course, nobody should be doing it.'It is a worrying situation if that's becoming more prevalent because it is incredibly dangerous.'As I say, it may not have been the case in this situation, we don't know, but anybody who is doing that, wherever it might be, is absolutely wrong to do so.'Snapchat has been approached for comment.
