"During the rape, an unknown witness, the only passenger on the bus, attempted to get the driver's attention," the Sheriff's Department said in a statement. The L.A. Times also reported:

An MTA spokesman said the driver, Ricky George, has worked for the agency for almost seven years and is cooperating fully with Los Angeles County Sheriff's officials. It's still unclear whether he violated department policy. Drivers are expected to dispatch police immediately -- or set off the bus' silent alarm -- when a serious crime is reported.
