I don't think there was any evidence that the police beat him. They'd pulled his trousers down whilst restraining him/holding him up/dragging him and left him suffocating on the floor, whilst he had a head injury from an earlier fight. The CCTV recorded conversations between the custody sergeant and some officers where they discussed getting him medical help as there was blood coming from his mouth and he was making gasping sounds - the custody sergeant and a female officer stated that he was pretending. There was also alleged monkey noises being made by an officer as he was dying.
After the inquiry ended and charges to the officers dropped, they got paid off £50-100k for stress and pensioned off. The guy who originally hit him (his mate) got charged with gbh and then charges dropped three weeks after, once the post mortem results were released. He sued the CPS and police and got compensation.
It was Jason Paul who was arrested for GBH, he got £30k in compensation for malicious arrest, as it was believed he was only arrested to deflect from the death in custody.
