Thirty-one-year-old NYPD officer Jonathan Diller was shot and fatally wounded during a traffic stop Monday, allegedly by a man with multiple prior arrests.

The New York Post reported the incident occurred around 5:50 p.m. after Diller approached the vehicle in which 34-year-old Guy Rivera was sitting as a passenger.

Rivera allegedly refused orders to exit the vehicle and Diller was in the process of removing him from the seat when Rivera shot him in the stomach, just below his protective vest.

PIX 11 noted Diller continued to fight to disarm Rivera even after being shot, knocking the pistol to the ground.
