Actor Scott Siegel is suspected of dealing drugs and was arrested Wednesday night in Westchester. Agents attempted to pull siegel over and he allegedly took off. Then , sources say, he crashed into a gate just off of route 22 in Tuckahoe, fled on foot, and struggled with agents. Siegel has a previous federal conviction for dealing steroids, ecstasy, and an animal tranquilizer used as a hallucinogen. He now faces charges of assaulting a federal agent. Other charges are pending.
