The programme which asks you, the viewer, to turn crime fighter.
Serious recent crimes are dramatically reconstructed - the police show the evidence to date, and you could provide the clues they need. Just seven weeks ago Sgt John Speed was gunned down in a busy Leeds street during the rush hour - the police need your help.
Forensic experts also need your help in identifying a mystery woman; and there's a visit to a 'red light' district in Birmingham where a sex killer is on the loose.
Nick Ross and Sue Cook will be waiting for your calls in the Crimewatch studio. Police officers David Hatcher and Helen Phelps report on the latest crime news from the Incident
Desk. If you can help, call the Crimewatch number:
[number removed], any time from 9.25 to the end of the evening. And see Crimewatch Update at 11.5 pm.
