Meanwhile, New York Police Commissioner James O’Neill confirmed a 29-year-old male got out of the van after driving the wrong way down the bicycle lane and hitting several people, before coming to a halt after ploughing into a school bus.
He was brandishing two handguns and an officer at the scene “shot him in the abdomen”. The guns were later revealed to be a “paintball gun and a pellet gun”.
