A vehicle smashed into an ambulance near a Brooklyn “trunk-or-treat” event sponsored by the NYPD, leaving six people injured, according to officials. The crash occurred just before 4 p.m. Thursday at the corner of Knickerbocker Avenue and Bleecker Street in Bushwick, police said. A dark-color ed vehicle was driving on the sidewalk when it struck the parked ambulance, which sustained heavy front-end damage to the passenger-side door. Six people were hurt and taken to nearby hospitals, but all were expected to survive, according to law enforcement sources. Three children — an 8-year-old boy and two girls, ages 6 and 12 — were among the injured, along with three women. The event was supposed to go until 5 p.m. but ended early due to the crash. It was not immediately clear why the driver of the other vehicle was traveling on the sidewalk, though there were no suspected ill or terror intentions, police said. A person of interest was taken into custody at the scene and was being tested for drugs and alcohol, a law enforcement source told NBC New York. An investigation was ongoing. ...read more read less
