Panorama goes behind the lines with Manchester's police and into the interview rooms with the rioters to tell the inside story of one of the cities most affected by the August riots. For the first time, a police force allows access to its footage from this summer's running battles - this time, on the streets of Manchester and Salford. The programme reveals how in Salford there was more to the rioting than opportunistic looting. And it follows the police investigation as they seek to identify and arrest the 700 rioters caught on camera at 300 separate crime scenes.
