The lobby of a Los Angeles Police Department station in Exposition Park is closed indefinitely after a man walked in with shopping cart lit with flames late Thursday, officials said.

The incident occurred around 11:25 p.m. at the LAPD’s Southwest Station, located at 1546 W. Martin Luther King Jr. Blvd.

A man walked into the station with a shopping cart on fire and the building’s front doors, ceiling and lobby chairs also caught fire, police said.

The man ran out of the building in an unknown direction.

Los Angeles Fire Department arson units responded to the investigation.
