About 24 Hours in Police Custody Season 4, Episode 4 : One Punch

Two lives change in a heartbeat after a single punch fells a man outside a nightclub. The blow kills the victim and the police arrest the attacker. Cameras follow every twist and turn as police from the Major Crime Unit try to disentangle what really happened. Was the punch an unjustified and aggressive assault on an innocent man or an act of self defence with tragic consequences? This is real life drama at its most intense. 24 Hours in Police Custody, the critically acclaimed documentary series that follows the work of Bedfordshire Police around the clock, has returned with a new approach to their investigations into major crimes. Cameras follow each case in forensic detail as the officers race against time to disentangle the evidence and build a case, which they then put to their suspects in interview.
