AMSTERDAM, Netherlands (AP) _ A burglar with a sledgehammer smashed a window at Rembrandt's home Sunday and stole a painting, and police said they had no leads in the theft.

It was the second smash-and-grab burglary at the Rembrandt House Museum in three months.

The stolen painting was ''Man with a Beard,'' dated 1647, Dutch television said. Its value was not immediately available.

The work had once been attributed to Rembrandt, but is now believed to have been painted by an unknown 17th century student of the Dutch master painter.

The burglar, who was seen running down the street with the painting, broke into the 17th-century brick building at about 1:30 a.m., Dutch TV said.

In July, the front door was smashed in and thieves grabbed two paintings by Rembrandt's teacher, Pieter Lastman. They have not been recovered.

The Rembrandt House has the world's largest permanent collection of Rembrandt's etchings and other graphic works.
