Today, detectives appeal for your help on unsolved cases. Do you have the vital information to put those responsible behind bars? And we meet the detectives using science to solve crime - including officers from Staffordshire who used cutting-edge techniques to reveal the face of an unidentified body which had remained a mystery for nearly half a century.

Each weekday morning, former detective Rav Wilding will also be asking viewers for help to solve crimes featured in dramatic reconstructions, identify criminals caught on CCTV and track down Wanted Faces. Meanwhile, roving reporter Michelle Ackerley will be travelling across the country and going behind the scenes with forces as they reveal how they're taking on the crooks.
