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 driver Ahmed H. Sharif with a folding knife on Aug. 24.
His attorney says Enright suffers from post-traumatic stress and chronic alcoholism.
Authorities say the 21-year-old uttered an Arabic greeting and told the driver: "Consider this a checkpoint." He's charged with attempted murder and assault, both as hate crimes.
The allegations have mystified some who know Enright, a senior at the School of Visual Arts.
An interfaith group helped send him to Afghanistan as part of a school video project. He spent time embedded with U.S. troops.
He'll be arraigned Sept 22.
