Summary
Since Crimewatch UK began viewers have helped solve serious crimes in some remarkable ways. In Crimewatch File, presented by Sue Cook and Nick Ross, detectives reveal for the first time the inside stories behind major investigations. In 1985 the flying squad was looking for a gang of armed robbers who were strapping remote-controlled explosive devices to their victims.

A 14-year-old saw Crimewatch and gave police information they could scarcely believe. It led to eight months surveillance, threw up the names of some notorious London criminals and led to the arrest of the gang. The case made criminal history when one of the robbers, Donald Barrett, turned supergrass for the second time. The handling of a double supergrass posed new problems for the officers close to Barrett and to those in charge of the investigation. This documentary follows the case through to the day Barrett and his former accomplices were sentenced at the Old Bailey.
