:^/ Not if it doesn't belong to him. If a fellow walked into a police station with the Mona Lisa under his arm, he may be arrested for stealing it, or he may collect a reward for recovering it, but he won't be allowed to keep it.
It's the same with anything; if it's stolen, it belongs to whomever it was stolen from, not to whomever posseses it currently.
