"He started talking to them and I could hear him saying, 'Terrorists!," he said.
"One woman called him 'stupid'. So he threw his hot coffee in her face. It was hot, hot coffee. She could have been burned! Then he swung his bag at her and it hit her in the face," the employee was quoted as saying by the New York Daily News.
The woman ran outside, and Gray put her in a headlock, police said.
Gray has been charged with assault as a hate crime, police said, adding that the victim has refused medical attention....
