Boston ― thieves dressed as police entered a museum early Sunday and stole 11 paintings, including major works by Rembrandt, Dagas, Manet, and Vermerr, FBI and the museum officials said.

The first judgement placed value of at least $100 million on the works stolen from the Isabella Teward Gardener Museum, said Boston police spokesman Jim Tordan.

The judgement was a loose(粗略的) one because the paintings have not been sold in nearly a century.

But art experts said such well-known works could not be sold in nearly a century, authorities said.

“It was not discovered until the cleaning people did some cleaning at 3 a.m.” said Paul Cavangah, special FBI agent in Boston.

“This is one of those thefts(盗窃)where people actually spent some time researching and took specific things,” he said.

He said the investigation(调查) would not be limited to the U.S.

William Bobinson of Harvard University’s Foggel Museum, called the objects stolen “major works”.
