Composite file e-fits of potential suspects which have built up since Madeleine McCann went missing two years ago. From left, a suspect described by Jane Tanner, one of the friends on holiday with the McCanns in May 2007, of a man walking with a child in his arms away from the holiday apartment where Madeleine was sleeping on the night she disappeared, image of a suspects face and a full length image made public in January last year based on a statement given by Gail Cooper, a British holidaymaker. Black and white computer-generated e-fits of two suspicious men seen hanging around Praia da Luz before Madeleine went missing which were released from official police files after Portuguese authorities shelved their investigation but which were never made public by detectives and a e-fit of a suspect released as part of a new TV documentary to mark the second anniversary of Madeleine's disappearance. The artist's impression shows a pock-marked and 'very ugly' man who appeared to be watching the apartment where the little girl was staying with her family on the day before she vanished.
