The driver of the other car, the man who snapped the photo of the officer aiming the gun at him, says he called 911 at the same time the CHP got a call from the female driver.

The confrontation began in Boyle Heights. Both drivers exited onto Findlay Avenue in Monterey Park. Authorities said officers arrived to intervene.

The CHP source told Kim the off-duty LAPD officer told them she pulled her gun fearing for her safety. She claims the other driver was trying to run her off the road.

By phone, the other driver told Kim he switched lanes in front of the off-duty officer and things got heated before she pulled a weapon.

Neither driver would go on camera Friday evening, Kim reported. She said the male driver didn’t want to make a statement until he could consult an attorney.
