Young people who spend 'endless hours in solitude, relentlessly online' need to be stopped from viewing explicitly violent material and copying Southport killer Axel Rudakubana, an inquiry into the atrocity heard today.The second phase of the inquiry into the 2024 stabbing massacre also heard how deadly 'tactical' knives were still easily accessible online, and advertised as 'combat' blades.It is more than two years since Rudakubana stabbed three little girls to death, and injured several others, at a Taylor Swift-themed dance class, after a string of missed opportunities to stop him.This stage of the probe will examine how to deal with those who pose a risk of extreme violence, but where ideology is not the primary driver, as well as the role of the internet and social media in influencing and enabling them.And inquiry chairman Sir Adrian Fulford said young people 'must be diverted from the thoughts and impulses which motivated' Rudakubana, who was described as a 'violence-fixated individual'.In his opening remarks in London, he said: 'We are confronted with a growing challenge from violence-fixated individuals, who all too often are not acting out of an adherence to a particular ideology.'Instead, the reasons for their interest in violence is various and as a result they can be extremely difficult to identify.'All too often they will be acting entirely alone, having spent endless hours in solitude, relentlessly online.' Axel Rudakubana was jailed for life and ordered to serve a minimum term of 52 years for the murders of Bebe King, six, Elsie Stancombe, seven, and Alice Aguiar, nine, who he stabbed to death at a Taylor Swift-themed dance holiday club He said solutions to combat the problem would be 'practicable, readily enforceable and proportionate'.He added: 'Our core objective is to contribute to real change given the devastation that can be wrought by those fixated on violence in this way.'The victims of (Rudakubana's) grotesque actions on 29 July 2024 deserve nothing less.'The inquiry is to examine whether other themes emerge from other cases involving VFIs who went on to kill in the UK.Rudakubana was just 17 when he murdered Bebe King, six, Elsie Stancombe, seven, and Alice Aguiar, nine, at a holiday club at the start of the summer holidays in the seaside town.Now 19, he was jailed for life and ordered to serve a minimum 52 years behind bars after admitting murder in January last year.The inquiry previously heard he used a simple chef's knife to carry out his atrocity, but had bought machetes evading age restriction provisions in the lead-up.Nicholas Moss KC, lead counsel to the inquiry, said there were concerns in relation to mainstream online knife retailers. Bebe King, six, Elsie Dot Stancombe, seven, and Alice da Silva Aguiar, nine, were all murdered in the atrocity on July 29, 2024He said members of the inquiry team had found knives available costing around £10, with some described as 'tactical' and 'ideal for piercing and cutting tasks'.Mr Moss said: 'Why does a knife on sale in the UK need a stealthy tactical look?'Why is it still being advertised in this way?'It is worth just pausing and reflecting on the fact that in July 2026, UK retail websites are still calling knives "fighter black", "Frenzy" and "Mayhem", and in many cases printing such names on the blade.'The inquiry will resume in September. The first phase of the inquiry looked into what happened concluded the attack 'was foreseeable and avoidable', and highlighted a litany of mistakes.The scathing report, published in April, concluded the attack 'would not have occurred' if the killer's parents had flagged concerns about his increasingly violent behaviour.It found the fiend's father Alphonse Rudakubana and mother Laetitia Muzayire, knew, at least a week before the attack, that their 'monster' son had amassed a small arsenal of 'deadly weapons' in his bedroom, and that he had planned an attack on his old school a week before, but did nothing.Inquiry chairman Sir Adrian said they must bear responsibility, because they obstructed officials, were 'too ready' to excuse their son's actions and failed to stand up to his behaviour or set any boundaries.

CCTV cameras caught him outside the Hart Space dance studio, in Southport, shortly before he launched the mass stabbing Inquiry chair Sir Adrian Fulford arriving at International Dispute Resolution Centre (IDRC) in central London, ahead of the opening of Phase 2 of the Southport InquiryThe atrocity did not come as a 'bolt out of the blue', rather Rudakubana's risk had been 'signposted' to state agencies for years and they 'could and should have prevented' him from carrying out his murder spree, the 700-page report concluded.Sir Adrian also said catastrophic failures by police, social services, mental health teams, youth justice services and other agencies left Rudakabana was free to kill with 'chilling brutality'.Officials also used Rudakubana's diagnosis of autism to excuse his behaviour and failed to recognise that, in truth, the condition heightened rather than lessened the risk he posed, Sir Adrian said.Last week, the Government accepted the recommendations of his first report and Home Secretary Shabana Mahmood said: 'We will do whatever is needed to protect the public.'
