The deputy who was seen in a viral video punching a 14-year-old boy was fired by the Sacramento County Sheriff’s Department.

In a statement released by the sheriff’s office in KCRA, the deputy was terminated from employment after an administrative investigation. The deputy has not been identified and the sheriff’s office did not release any other details about the investigation.

In a CNN report, the sheriff’s department and the Rancho Cordova Police Department said that they were investigating the use of force by the deputy “in order to gain a complete and thorough understanding of the events that took place during this incident.”

The firing comes after a video surfaced of the April 27 encounter in which an officer is seen on top of the teen, punching him as he lies on the ground. The video was posted on Twitter on April 28 and after a few days, it was viewed more than 2 million times. The video does not show the beginning of the altercation or its conclusion.

The department said the 14-year-old was “uncooperative” and refused to give out his information. The teen became “physically resistive” causing the deputy to lose control of his handcuffs when he then attempted to maintain control of the teen while waiting for backup.

At the time, the deputy was patrolling an area of the city after complaints of alcohol, tobacco, and drug sales to minors and “saw what he believed to be a hand-to-hand exchange between an adult and juvenile,” a statement from the police department and the sheriff’s office said.

The deputy lost sight of the adult who left the area, then attempted to detain the juvenile for further investigation, the statement added.

According to a statement on the police department’s website in April, the teen initially told the deputy he was 18 years old and the deputy later recovered tobacco products from him. The teen was later on released to his guardians, but the statement did not detail charges against the teen.
