TEMPLE CITY — A deputy fired his gun at a suspect Monday as they fought during an attempted arrest, officials said.

It was unclear if the suspect, who remained at large, was wounded, Los Angeles County sheriff’s officials said in a written statement. The deputy was treated for minor injuries suffered in the confrontation.

The incident began when a patrol deputy stopped a bicyclist about 4:30 p.m. in the 10600 block of Lower Azusa Road, in a mixed commercial and residential neighborhood near the El Monte border.

“The deputy began to affect an arrest of the bicyclist (suspect) for a narcotics charge,” according to the sheriff’s statement. “The deputy and the suspect became involved in a physical struggle, during which a deputy-involved shooting occurred.”

The suspect ran off and the search for him continued Tuesday, officials said. It was not known if he had been shot.

Officials described the suspect as a Latino man of about 35 years old, about 5 feet 8 inches tall and 135 pounds.

As is common practice when a sheriff’s deputy is involved in an on-duty shooting, the incident is being investigated by the sheriff’s homicide and internal affairs bureaus, as well as the Los Angeles County District Attorney’s Office and the County of Los Angeles Office of Independent Review.
