The five joyriders who were killed when the car they drove the wrong way down a dual carriageway smashed into a police vehicle have been pictured.Two officers also died in the crash – and PCs Matthew Blades, 38, and Tom Clough, 37, have been hailed for their bravery after being killed in the line of duty yesterday. All seven were declared dead at the scene on the A66 in Middlesbrough.The tragedy comes after similar incidents linked to an online craze in which youngsters incite police cars to chase them before sharing video footage of the pursuits. The five in the VW have been named locally as Michael Ray, Theo Rae, Cole Worthy, Jakub Matusiak and Makai Saddington.Last night it emerged Mr Saddington had posted a string of TikTok videos appearing to show him taking part in high-speed police chases months before his death.It is understood he and his companions had close links to the traveller community.In the early hours of Saturday morning, the group of teenagers became involved in a pursuit with two police cars chasing the 'suspicious' vehicle.Ring doorbell footage shows that at 3.36am the VW Passat was driven at speed through Middlesbrough's streets before officers halted the chase when the vehicle turned on to the A66. Makai Saddington, 18, had posted videos on TikTok of him being chased by police over the past few months Jakub Matusiak was described by his sister as her 'best friend always and forever' Close friends Theo Rae (left) and Cole Worthy both died in the crash on Saturday night Michael Ray was praised by those who knew him as a 'lovely, down-to-earth lad' The moment police are seen pursuing a car down a narrow road just minutes before seven people, including two police officers, were killed in a head-on smash Just three minutes after the pursuit was caught on camera, at 3.39am, the car ploughed into the path of a different marked armed-response vehicle, which was on the correct side of the A66.Cleveland Police lowered flags to half-mast at their Middlesbrough headquarters in tribute to their fallen colleagues, who are understood not to have been part of the pursuit.As an investigation into the incident continues, social media posts from the teenagers reveal some insight into their activities before the tragedy happened.In one clip, filmed in May by a passenger and set to rap music, 18-year-old Mr Saddington is seen in an Audi being driven at speed through a housing estate with a police car's blue lights flashing in pursuit.The vehicle is then seen veering across a grassy playing field in an apparent bid to shake off officers.Another video on an account associated with him shows a green Nissan being driven around before being set alight, while separate images posted elsewhere show him and a friend posing in cars wearing black balaclavas.The clips reflect a trend of young men filming themselves being pursued by police at high speed and posting the clips on social media in pursuit of views and likes. It happened just days after five teenagers died in a head-on collision on a motorway in Ireland.The masked youngsters were in a stolen BMW travelling the wrong way down the M9 in County Kildare at 2am last Sunday.
