An Metropolitan Transportation Authority conductor is charged with assault after police say he punched a passenger on an R train in Queens.
Police say Thomas Christopher, 35, hit the passenger, identified by sources as 18-year-old Zaid al-Doori, after arguing with him near the 36th Street station Sunday morning.
Published reports say Christopher was upset because al-Doori had put his feet up on the seats.
This is not Christopher's first brush with the law, as police say he was arrested for assault last April.
The MTA says Christopher could face disciplinary charges.
