Your help is needed to find an armed gang who robbed a post office van in Burnley, Lancashire, and then shot a policeman in the leg. The villains drove off and hijacked two cars, forcing the occupants out at gunpoint, before finally escaping in a Ford XR3i.

This month viewers are asked to help identify the person who killed pensioner Shirley Leach on Thursday 6 January this year. Shirley was on her way home after visiting her daughter in hospital when she was attacked. She'd caught the bus to Bury Interchange and was waiting for her connection at about 9:20pm when she visited the ladies toilet. Her body was found a few hours later. A man wearing a flat cap, around 40-50 years old was seen near the toilets several times that evening.
