Police forces around the country appeal for viewers' help to solve serious crime.

Three months ago, 14-year-old Tracy Meade went missing from her home in west London. Two weeks later her body was found in the Grand Union Canal. She had been murdered. Hours earlier she had been seen in Shepherd's Bush - police hope someone may have seen who she was with. There's also a report on a chase through London's Covent Garden, which led to the fatal stabbing of Detective
Constable Jim Morrison last December, after he discovered a thief rifling through a woman's handbag.

If any viewer can help with these, or other cases featured, telephone lines are open on [number removed] from 9.30pm until midnight.
