Officials say one or more thieves broke into a Swedish museum and stole work done by American pop icons Andy Warhol and Roy Lichtenstein.
Police say the break-in happened at the Abergs Museum near Stockholm early Friday.
Museum officials say two Warhol and three Lichtenstein paintings were stolen as well as a Disney movie-poster.
The museum estimates the value of the stolen artwork at around $500,000.
Police had no immediate suspects in the case.
