London: Detectives hunting for missing Madeleine McCann have issued two images of a man they urgently want to trace as part of the investigation.

The e-fit pictures, showing a white male, aged between 20 and 40, with short brown hair, were compiled by separate witnesses who both spotted him in the resort of Praia da Luz on the evening the three year-old disappeared.

While the two pictures appear to show a person with slightly different features detectives are convinced it is the same person they are seeking.

The images will be broadcast on a BBC crimewatch program as part of a renewed international appeal.
