MOUNT WASHINGTON, LOS ANGELES (KABC) — Los Angeles police officers on Wednesday morning were involved in an hourslong standoff with a man armed with a gun who barricaded himself inside a car at a Metro light rail station in Mount Washington, authorities said.

The incident began just after 7:30 a.m. at the A Line’s Southwest Museum Station at 4600 Marmiom Way, according to the Los Angeles Police Department. The suspect was described as a passenger; the driver was able to safely exit the vehicle.

More than a dozen officers were seen in position behind the car in which the suspect was barricaded. As of 10 a.m., authorities were waiting for a SWAT team that was summoned to the scene.

All train service was shut down at the station, and Marmiom Way was closed as the barricade situation continued.
