An Amtrak train was evacuated in Chatsworth on Friday after a passenger said they saw a man with a gun, authorities said.
At first only about 30 people on the same car as the gunman were evacuated, then police later cleared all 187 passengers from the train after finding a man in the bathroom with a gun.
Deputies and police officers were holding the train at the Chatsworth station awaiting the arrival of Amtrak police, who they said would take over the investigation, according to Deputy Ryan Rouzan. But hours later, city and county authorities remained on scene, attempting to coax the man out of the bathroom.
Three hours after the situation was reported, the train remained at the Chatsworth station and buses were brought to shuttle passengers to their destination.
The train had been heading to Union Station, Ramon Montenegro of the Sheriff's transit policing division said, and from there it was supposed to travel to San Diego.
