24 Hours In Police Custody | Preview (Channel 4)

24 Hours In Police Custody returns for a two-part special following the work of Bedfordshire Police, from the cells at Luton to the operational heart of major investigations.

This time, we follow the investigation into one of the biggest murder enquiries ever conducted by the Bedfordshire Police. All the twists and turns of a manhunt that became darker and more disturbing as detectives investigated are exclusively revealed in forensic detail.

Detectives from the Major Crime Unit have a suspect in custody but they're shocked when what their investigation reveals is even more devastating and important than their worst fears.

24 Hours In Police Custody returns Sunday 5th October at 9pm on Channel 4.
