24 Hours in Police Custody

Police officers search for a man in Luton who disguises himself as a delivery driver to force his way into people's homes and commit brutal assaults. However, when the police investigation fails to make headway, the family of one of the victims launch a campaign for information on social media - which increases the likelihood of the criminal seeing he is at risk of discovery and going to ground.

A violent daytime brawl with knives erupts on the streets of Luton as a chicken shop war heats up. But the case takes an even more disturbing twist when a police raid lands a huge cache of drugs.

Part one of a two-part report into the case of a man who sexually preyed on young people in Luton, which eventually became Bedfordshire Police's largest ever operation into historic abuse. The film begins with the work of a detective in the Child Sexual Exploitation unit, who discovers that a victim's testimony identifies a man who had been arrested eight times previously for sexual offences but had never been convicted.

Bedfordshire Police's largest ever operation into historic abuse continues, with DS Rachael Foy spending three years working to persuade victims to testify against the suspect. However, she knows that the system too often lets victims down even when they are brave enough to come forward - and in this case, many of the victims have died before they are able to do so.

On a quiet Sunday lunchtime in a Cambridgeshire suburb, a man lies bleeding to death. A major manhunt is triggered, where the strength of family blood ties is brutally exposed.

The real-life drama follows police investigations into one of the most disturbing and hard-to-prove crimes - baby-shaking cases - and examines parents' often-divided loyalties.
