Detectives have dismissed as fake sightings in Turk and Caicos of a father who allegedly abducted his seven-year-old daughter.

There were two reports that Clark Rockefeller and his daughter Reigh Boss were seen on the island of Providenciales on Thursday.

But the Associated Press reported yesterday that police in Boston had investigated the sightings and found them not to be credible. Boston Police spokesman Eddy Chrispin said: "It definitely was not him."

Rockefeller and his daughter were last seen at New York City's Grand Central Terminal on Sunday, hours after he allegedly ran off with her during a supervised visit. The girl had been living in London with her mother.

Police initially suspected he was trying to flee to Bermuda or Peru on a 72-foot catamaran called Serenity. But authorities say he may have planted false clues to throw off investigators.

Many other reported sightings have been made, but none have panned out.
