Man struck and critically injured by car while walking in the Oceanview neighborhood.

A man was critically injured when a vehicle struck him in San Francisco’s Oceanview neighborhood on Monday night, a police spokesman said Tuesday.

The collision was reported at 9:12 p.m. at Alemany Boulevard and Brotherhood Way.

The 47-year-old victim and his brother were walking south in a crosswalk when a driver traveling west on Brotherhood Way struck him, police spokesman Sgt. Eric O’Neal said.

The victim was taken to San Francisco General Hospital to be treated for a life-threatening head injury, O’Neal said.

The driver of the car, a four-door sedan, stopped at the scene and cooperated with investigators, and was not arrested, O’Neal said.

The collision remains under investigation.

The case is the latest in a string of pedestrian-vehicle collisions in San Francisco. Several have resulted in deaths in the past month.

The San Francisco Police Commission and the Board of Supervisors’ neighborhood services and safety committee are holding a joint hearing on Thursday to discuss the issue of pedestrian safety.
