A naked man doing push-ups in the middle of a North Portland street was struck and killed by a car early Sunday.

Police first responded to the report of a naked man running in traffic near North Columbia Boulevard and Portsmouth Avenue at 4:04 a.m.

While en route, they received a second report that the naked man was doing push-ups in the road.

Then, they received a third report: he had been struck by a car.

Officers and medical personnel arrived and found the man dead.

The driver who struck the man remained at the scene and was cooperative. The driver was not impaired by alcohol or drugs, according to police.

The roadway was closed for several hours during the investigation, but reopened later Sunday.

An autopsy will be conducted, including toxicology, to determine the pedestrian's cause of death.

The victim's name has not been released.
