The mayor of the city of San Gabriel was in custody Friday on charges of felony robbery and assault after he allegedly took a woman’s purse and sped down a residential street with her clinging to the side of his sport-utility vehicle.

Mayor Albert Y.M. Huang was being held at the San Gabriel police station, said Lt. Ariel Duran of the San Gabriel Police Department.

Police said they received a call about 1:15 a.m. Friday about a heated argument between Huang and a woman. Investigators determined Huang was arguing over money with the woman outside a restaurant in the 300 block of West Valley Boulevard.

Huang allegedly took the woman’s purse, which contained her car keys, cash and personal belongings and got into her car, Duran said.

The woman attempted to prevent him from leaving by reaching through the vehicle’s window. Huang then allegedly pushed the woman, got out of her car and entered his own, a Nissan SUV.

The woman then reached through the passenger window of Huang’s SUV and stood on its running boards, Duran said.
