New York City Mayor Bill de Blasio called the attack, which killed eight people and injured at least a dozen others, "an act of terror — and a particularly cowardly act of terror."
New York City Police Commissioner James O'Neill said that a 29-year-old man was arrested after being shot in the abdomen by a uniformed officer in the 3:05 p.m. attack.

"This incident is over," O'Neill said.
