The article doesn’t mention the police’s initial response.
Here’s a excerpt from the BBC:-
Previously, the court heard the University of Southampton first year student was walking back to his accommodation from a night out, after drinking to a level below the drink-drive limit.
Jurors were told the attack, which resulted in five stab wounds or cuts, was not witnessed and Nowak tried to escape by climbing over a fence.
Police initially handcuffed the victim before discovering his fatal injury a short time later, the court previously heard.
Digwa, of St Denys Road, Southampton, said he did not tell police he had stabbed Nowak because he was “scared”.
His mother, Kiran Kaur, 53, is also on trial and denies assisting an offender by removing a weapon from the murder scene.

From what I read on another thread is that the phone video is the fly in the ointment for old Vickrum.
After he bled out in their custody because they assumed since he was white he wasn't worth checking on.
