NEW YORK (AP) - A defense lawyer says a student accused of cutting a Muslim taxi driver's neck in New York City has post-traumatic stress disorder and chronic alcoholism.

A Manhattan judge said Monday he'll decide at arraignment whether to grant bail for Michael Enright, of Brewster, N.Y. He's accused of attacking the driver with a folding knife last month.

His attorney says the stress disorder was brought on by war horrors he witnessed while filming a documentary in Afghanistan. The lawyer also says his 21-year-old client could get treatment for alcoholism if he is allowed out on $250,000 bail.

Authorities say Enright uttered an Arabic greeting and told the driver: "Consider this a checkpoint." The School of Visual Arts student is charged with attempted murder and assault as hate crimes.
