At least three people were critically injured in a crash involving two vehicles near a Metro bus stop in Vermont Square on Wednesday night.

Authorities responded to the collision near the 450 block of 51st Street around 7:05 p.m., according to the Los Angeles Police Department.

At one point, a pedestrian using a crosswalk was struck by a vehicle. The impact pushed that person under the nearby bus, LAPD said.

Three people were transported to local hospitals in serious to critical condition. Four others who were involved in the crash declined medical transportation.

Details remain limited and it’s unclear what initially caused the vehicles to crash.

There were no passengers on the bus at the time, police said, and the bus driver was uninjured.

The cause of the crash remains under investigation.
