The true crime documentary that has left viewers feeling physically unwell is set to return to screens with a brand new episode this evening. Channel 5's Police Suspect No.1 will be back for its fifth season, continuing its unflinching look at major police investigations.
A Series That Leaves Viewers Shocked
First airing in 2020, Police Suspect No.1 has built a dedicated following by shadowing detectives as they tackle serious crimes. The new season, which began earlier this month, immediately plunged audiences into a harrowing case from Gwent Police. Viewers witnessed a terrified woman's emergency call reporting an intruder, followed by a brutal assault on a police officer captured on bodycam footage.
The reaction on social media was one of profound shock. One fan described the perpetrator as an "animal," while others simply stated the episode was "awful" and that it "made me feel sick." The show has been widely dubbed a "savage" and "brutal" watch, even by hardened true crime enthusiasts.
Tonight's Episode: A Violent Road Rage Case
The series continues tonight, Monday, January 19, 2026, at 9pm on Channel 5. This latest instalment will shift focus to Ellesmere Port, where CID officers are tasked with building a watertight case following a violent road rage incident.
According to the channel's TV guide, the episode will involve dangerously high speeds, promising another intense, life-or-death investigation for the officers featured. It is set to be another gripping chapter in the series that has become essential viewing for fans of programmes like 24 Hours in Police Custody and Catching a Killer.
How to Watch the New Episode
For those who cannot catch the broadcast, every episode of Police Suspect No.1 is available to stream online via Channel 5's on-demand service. The platform also hosts the show's spin-off series, Murder Suspect No.1, offering even more content for dedicated fans to binge.
With its return tonight, Police Suspect No.1 reaffirms its position as one of the most visceral and talked-about true crime documentaries on British television, offering a raw and unsettling window into the frontline of British policing.
