The police's rapid announcement of the age, ethnicity, and nationality of the Liverpool parade suspect shows they've learned lessons from the 2024 Southport attack. Within two hours of a car hitting a crowd of Liverpool fans as they celebrated their team parading the Premier League trophy, Merseyside Police said they had arrested a "53-year-old white British man from the Liverpool area". Last summer, the same force was criticised in the aftermath of the Southport stabbings when online speculation and misinformation filled a void after the same force released few details about a 17-year-old – later revealed to be Axel Rudakubana – that they had in custody. On today's Sky News Daily, Matt Barbet is joined by our north of England correspondent Katerina Vittozzi, who is in Liverpool, and Helen King, former assistant chief constable for Merseyside Police, who talks about the challenges of policing online speculation.
