An off-duty New York City police officer arrested on manslaughter and driving-while-intoxicated charges after a crash that killed a college student has been fired.

Police Commissioner William Bratton announced the termination of Nicholas Batka on Wednesday.

Batka previously had been suspended. His attorney hasn't returned a phone call seeking comment on the termination.

The SUV crash early Saturday in Brooklyn's Williamsburg neighborhood killed 21-year-old pedestrian Andrew Esquivel and seriously injured three of his friends.

Esquivel was a native of Healdsburg, California. He attended the Massachusetts Institute of Technology and had an internship at a New York company.

Bratton says two other off-duty officers who were with Batka have been stripped of their guns and shields while an investigation continues.
