Missing Madeleine McCann could not have been abducted, Portuguese police are said to have concluded.

The final police report suggests the youngster died in the family's holiday apartment in Praia Da Luz on the Algarve, it was claimed.

Police have no evidence the youngster's parents, Gerry and Kate McCann, were involved in the disappearance of their daughter on May 3 last year.

The couple, who strongly deny having a hand in her possible death, say they last saw Madeleine when they left the three-year-old sleeping in the flat while they went out for dinner.

But an exhaustive 13-month investigation showed it was 'theoretically impossible' the youngster was abducted, the newspaper Correio da Manha said.

Forensic tests on the apartment's window, through which an abductor might have carried Madeleine, revealed no traces of the girl.

The McCanns, both 40-year-old doctors from Rothley, Leicestershire, were made suspects in the case in September. They were unavailable for comment.
