The London's Sun newspaper called police after being offered pictures of Britain's Prince William and his girlfriend, Kate Middleton, it said Monday.

The British tabloid said it was offered more than 40 photographs showing the couple vacationing on the Caribbean island of Mustique — where they reportedly spent time early last month.

The paper said the pictures were taken from a digital camera stolen from a car in London just before noon on Friday. Less than an hour later, The Sun said, it was contacted by two men claiming to have found the photos on a memory card they fished out of a gutter. The men wanted $90,000 for the pictures, the paper said.

But The Sun said it had passed up the opportunity to pick up the pictures and instead called Scotland Yard, which went on to make an arrest.
