Authorities have a suspect name but no motive for the fatal shooting of a bus driver in West Hollywood over the weekend.
LA County sheriff's investigators have identified 41-year-old Anthony Chambers of Los Angeles as a suspect in the Sunday morning shooting.
Chambers was booked for investigation of murder and is being held Monday on $1 million bail. Authorities believe Chambers and the bus driver were the only people on the Metro bus at the time of the shooting. The victim was reportedly hit in the torso.
Witnesses told investigators they saw Chambers climb out of a bus window and run down the street. He was reportedly arrested soon after.
The driver was identified Monday as 51-year-old Alan Thomas, a five-year veteran, according to the L.A. Times.
Thomas had just steered the bus onto Santa Monica Boulevard out of a layover area at La Cienega Boulevard when he was attacked, said Metro spokesperson Marc Littman, NBC LA reports.
The transit agency happened to have a supervisor stationed on Santa Monica to help set up a temporary road closure to make way for the Amgen Tour of California bicycle race, said another spokesman, Rick Jaeger.
At a few minutes after 9 a.m., the supervisor saw the bus -- which had been heading east -- roll backward into a parked car, and ran over to see what was going on.
He found the wounded driver, who was quickly taken to Cedars Sinai Medical Center. He died there at about 9:30 a.m., Littman said.
It was the first time a Metro driver had been slain on the job, Littman said.
