El Monte police officer injured during a fight at a shopping center

An El Monte police officer was injured after a fight at a shopping center Friday.

According to the Los Angeles County Fire Department, the fight happened around 9:30 p.m. in the 12000 block of Valley Boulevard, when authorities were made aware of a possible robbery taking place at the DD's Discount location. 

El Monte police arrived at the scene to find a man, since identified as Roy Aguirre Jr., who is believed to have attacked a store clerk multiple times with an undisclosed hard object. The first officer who arrived found Aguirre on top of the clerk, punching her with one hand while strangling her with the other.

The clerk, whom officers learned was a domestic partner of Aguirre's, suffered injuries to the head, arms and hands due to his attacks. 

Aguirre attacked officers when they approached him, leaving one injured. 

He was taken to a nearby hospital and treated for injuries sustained in the incident. He was released on Saturday.

Police detained the suspect shortly after the fight, who was also taken to a hospital for treatment before his arrest. 

Aguirre has been charged with attempted murder and resisting arrest.
