The New York Times reports that "a multimillion-dollar collection of artwork by Andy Warhol was stolen from the home of a wealthy art collector in West Los Angeles last week." There were "several other valuable works of art" in the home, but "none of those were disturbed," according to the police.
UPDATE: More from Art Theft Central.
UPDATE 2: Derek Fincham runs through the possibilities. Judith Dobrzynski has some background on the victimized collector.
