Tonight: an attack by an armed gang on a couple in Cowdenbeath, Fife, one night last December. Among the clues that the police hope will jog someone's memory are the northern English accents of the robbers and the white transit van and red Ford Escort they used.

Crimewatch UK also reconstructs the murder of Doris Shelley two months ago. She lived alone in a 17th-century mill house in Suffolk and a man had been seen on two occasions hiding in her garden.

Tonight: the murder of 42-year-old Londoner Bulic Forsythe who was last seen leaving his office at Lambeth Council on the evening of Wednesday 24 February. The next day he failed to turn up for work. Then in the early hours of Friday, witnesses heard shouts and footsteps running away from the block where he lived. Soon after, fire was discovered spreading through his flat and his battered body was found in the bedroom. Crimewatch UK has artists' impressions of two men seen with him.
