Police had received multiple 911 calls about the rowdy even on the 900 block of Lambaren Avenue and responded to the scene shortly before 1:30 a.m., Police Officer Steve Goard said. Callers reported people screaming, bottles breaking and a possible fight.
Arriving on the scene, police found around 100 people in the area, including at least one male juvenile who was so drunk he was unable to walk.
When officers attempted to check on the male juvenile, however, a group of individuals became confrontational and a 17-year-old male urged others to challenge the police.
When officers attempted to handcuff the teen, he allegedly punched the officer in the face and torso multiple times. A 19-year-old male, later identified as Adrian Manzano, then allegedly jumped on the officer's back and choked the officer.
All three fell to the ground, and the two men continued to attack the officer until other officers were able to assist.
The attacked officer was taken to a hospital, where he was treated and released with a broken leg.
Manzano and the male juvenile, whose name was not released due to his age, were arrested on suspicion of battering a police officer with injury, resisting or deterring a police officer with force and willful resistance to a peace officer causing serious bodily injury.
Anyone who witnessed this incident or has information on it is asked to call Livermore Police Officer Steve Goard at (925) 294-7531.
