The 62-year-old man accused of shooting 10 people on the New York subway was placed in pre-trial detention Thursday after being arraigned on terror charges related to attacking a mass transit system. 

Frank James is alleged to have detonated two smoke canisters on the train as it pulled into a Brooklyn station before firing into the crowd in an incident that left 23 people injured but caused no deaths.

During a brief hearing, James told the court that he understood the charges, while his lawyers requested a psychiatric evaluation.
