NYPD officers shot and killed a man with a large knife who they were chasing near Times Square Saturday afternoon.Police said the man, who they observed smoking marijuana, became belligerent when officers approached him. He was shot dead after he threatened officers with the knife, police said. The man had no identifcation on him, officials said. No officers were injured in the incident, which took place over a number of blocks and ended with the shooting at 38th Street and 7th Avenue, an area generally crowded with pedestrians. Witnesses to the shooting described a chaotic scene in Midtown. “I was standing at the corner of 42nd Street and saw this guy running in middle of street, police chasing him” said Edgar Delgado, who works in the area. “He had a machete type knife. He didn’t want to stop. Police told him to drop the knife. He didn’t. They shot him.” A witness’ cell phone video acquired by NBC 4 New York shows police chasing the man along 7th Avenue and then opening fire, shooting approximately 10 rounds. “It was scary because a shooting starts here someone could get hurt quickly,” Delgado said.
