Bahamas ? A fugitive U.S. teenager who has successfully eluded teams of local police and FBI agents may have slipped off the island where he allegedly crash-landed a stolen plane nearly a week ago, police said Friday.

Authorities are investigating a report that Colton Harris-Moore, dubbed the “Barefoot Bandit,” has fled Great Abaco Island and was spotted on Eleuthera, about 40 miles to the south, two police officials said.

The officials spoke on condition of anonymity because they were not authorized to comment publicly on the search.

It was unclear how the 19-year-old fugitive, accused of dozens of burglaries in the U.S., might have escaped the island, but a powerboat was stolen in Marsh Harbour.

The 44-foot boat was reported missing Thursday from the marina on Great Abaco Island, said Harry Mountain, a regional manager for The Moorings hotel and marina resort in Marsh Harbour.
