Channel 4's award-winning true crime documentary series 24 Hours in Police Custody returns to screens tonight (Thursday, June 25) with a particularly harrowing episode, accompanied by a stark warning for viewers.
Episode Details and Warning
Titled Sudden Death: Think Murder, the repeat episode originally aired in 2019. It follows detectives investigating the sudden death of a 48-year-old woman in Cambridgeshire, with the hunt for clues taking the investigation across Europe. The official synopsis states: "Detectives investigate the sudden death of a 48-year-old woman in Cambridgeshire, and the hunt for clues takes the investigation right across Europe."
Channel 4 has issued a caution: "Graphic images from the start and scenes that viewers may find upsetting. This programme isn't suitable for younger viewers." The episode immediately plunges audiences into police concerns that the death was far more sinister than it first appeared.
Series Background
Since its debut in 2014, 24 Hours in Police Custody has become a firm favourite among true crime enthusiasts. The series builds its reputation by plunging viewers into real-life investigations, shadowing detectives as they tackle serious crimes from murder and sexual assault to drug gangs. Each episode typically follows a case from the initial 999 call to its resolution, revealing the raw reality and urgency faced by officers.
Earlier this year, fresh instalments left fans shocked and disturbed before a scheduling shake-up temporarily removed the show from TV listings. The programme continues to garner exceptional acclaim, with fans hailing it as the "best" show of its genre. One IMDb user commented: "This is a rare reality show that makes all others look like bad tv." Another observed: "It's true crime, at its most honest and also most horrific."
Broadcast Information
24 Hours in Police Custody airs tonight at 9pm on Channel 4. Episodes are also available to stream online.
