An 18-year-old Southampton student, Henry Nowak, was handcuffed after being stabbed by Vickrum Digwa, 23, who lied to police at the scene, claiming he had been the victim of a racist attack.

Digwa has been jailed for life with a minimum 21-year term.

Nowak’s parents said they hold Digwa solely responsible for the murder of their son, but the way he was treated by police was inhumane and degrading. Hampshire police has apologised to Henry’s family and the case has now been referred to the Independent Office for Police Conduct.

BBC Verify has analysed bodycam footage that was released by the police, with the permission of Nowak’s family, and looked at the key moments before Henry Nowak’s death. Merlyn Thomas reports.
