Investigators are hunting a new suspect in the Madeleine McCann case.

PRIVATE investigators working on behalf of Gerry and Kate McCann are hunting a new suspect.

While filming a Channel 4 documentary the ex-policemen worked with researchers to comb through the Portuguese police files.

The suspect was seen to be acting suspiciously in the days before the youngster went missing nearly two years ago.

Witnesses saw him loitering on a road near the holiday apartments where the family stayed.

Spokesman for Kate and Gerry Clarence Mitchell said: “To the Portuguese police this is not new information but on the advice of their private investigators Kate and Gerry felt that it was important to get into the public domain.”

The Channel Four Cutting Edge documentary will be shown on May 7.
