A man was taken to a local trauma center in critical condition after he fell off a Metro platform and was run over by the A Line train in Downtown Long Beach Friday night, authorities said.

The man in his mid-30’s somehow fell off the platform at Fourth Street and Pacific Avenue before he was run over by the front wheels of an incoming train, fire department spokesman Jake Heflin said.

Before he was hit, people had flagged down police officers to tell them a man was on the train tracks.

“Before officers could get to the male, he was struck by an oncoming train, sustaining injuries to his upper and lower torso,” police spokeswoman Jennifer De Prez said.

First responders arrived on the scene at about 5:30 p.m. The man remained trapped under the car until they were able to extract him around 5:53 p.m. He was transported to a local hospital in critical but stable condition, De Prez said.

Los Angeles Metro tweeted that the A Line would have 15 minutes delays because of the incident. It recommended riders use the Los Angeles-bound platform at Anaheim Street.

Northbound Pacific Avenue is closed between Fourth and Fifth streets while police investigate, according to De Prez.
