Judicial police said Saturday that two men managed to get past two security gates Friday at the home of the collector then knocked on the door. The collector, in his sixties, was beaten up and the Picasso lithograph and four works by other artists were taken.
Officials have not put a value on the heist.
A Picasso, Matisse, Modigliani and two other masters' works were stolen Thursday from the Paris museum, whose security alarms were broken.
