A pedestrian was seriously injured after being hit by a Portland police car on West Burnside early Saturday.

The names of the victim and officer driving the car were not immediately released.

According to police, based on the preliminary investigation and information from witnesses, the officer was driving westbound on Burnside Street, with a green light, when the man stepped from the curb at Northwest 2nd Avenue into the street and was hit by the marked patrol car.

The accident happened at 2:23 a.m. on May 10, police say.

After the collision, the officer immediately called for medical personnel to respond to treat the man, an adult male, who appeared to be suffering traumatic injuries. Medical personnel transported the man to a Portland hospital, where he is recovering from injuries and what police say is an apparent heroin overdose. He is expected to survive.

All westbound lanes of West Burnside were closed and the Traffic Division's Major Crash Team responded to conduct the investigation.

The police car was towed for further investigation and the street was reopened to all traffic at approximately 5:15 a.m.
