A lone gunman approached a police vehicle where two officers were sitting and opened fire. One of the officers died at the scene and the second one is in a critical condition in hospital.
The attack has been described as ‘execution style’.
It is understood that the attacker fled on foot into a nearby subway station and was reportedly killed there, though it remains unclear whether he died as a result of police fire or he took his own life.
Police have not yet released a motive for the killing.
