SANTA CLARA — A Santa Clara County Sheriff’s deputy is on administrative leave following a weekend arrest in Santa Clara where police say he drunkenly drove into a Jack in the Box drive-thru lane while brandishing a gun.

Benjamin Lee, 33, was arrested about 2:40 a.m. Sunday at the fast-food chain’s location in the 900 block of El Camino Real, according to Santa Clara police.

Lt. Kurt Clarke said Lee was arrested without incident and booked on suspicion of DUI and brandishing a weapon. Lee is currently out of custody.

The Sheriff’s Office released a statement noting that Lee was not on duty when the arrest occurred, and that he has been placed on administrative leave pending the results of both an internal investigation and the criminal probe by Santa Clara police.

Lee’s arrest adds to a growing list of trials and tribulations faced by the Sheriff’s Office, which is embroiled in ongoing controversy and public scrutiny over its supervision of the county jails, magnified by the August beating death of a mentally ill inmate allegedly at the hands of three correctional deputies.

Roger Winslow, vice president of the Deputy Sheriffs’ Association, which represents enforcement deputies in the county like Lee, said in a statement that the union is “saddened” by the arrest

“Our deputies make arrests for these crimes regularly. They see firsthand the consequences caused by impaired drivers,” Winslow said. “DUI by anyone is unacceptable; doubly so when it involves a deputy sheriff. We are held to a higher standard and rightly so.”

Winslow also cautioned against a rush to judgment in the case.

“We fully expect that appropriate action will be taken after all the facts are determined,” he said.
