The shot was fired from outside the bus, which came to a stop at the intersection of Martin Luther King Jr. Boulevard and Vermont Avenue, said sheriff's Metro Transit Bureau Lt. Lester Trull. The shooting occurred around 10:17 p.m. Friday.
The woman had stopped her car at the intersection when she was approached by three suspects, said Los Angeles police Sara Faden of the Media Relations Section.
"They asked her a question and she got scared and drove off,'' Faden said. "One of them (suspects) pulled out a handgun and fired at her."
The boy was struck as the bus, which had been diverted from its original route because of police activity, was making a left turn from Saint Andrews Place to 39th Street, Ubaldo said.
The bus was carrying 40 passengers, Trull said.
The woman drove herself to the nearby LAPD Southwest Division station, according to broadcast reports.
The teenager was treated and released from an area hospital, Faden said.
