Police in Livermore are searching for suspects who caused extensive property damage by launching large river rocks this weekend.
The attacks were the second early Saturday following another rock-throwing a week ago in Livermore.
A Livermore police officer's leg was broken early Saturday as he and his partners attempted to break up a large, drunken gathering Saturday morning in the 900 block of Lambaren Avenue .
In the latest rock-throwing melee, mailboxes, vehicles and homes were vandalized in nine separate incidents Saturday between 1 a.m. and 2 a.m., police said.
Police believe the suspects may be using a launching device and said that in one instance, a large rock traveled through a home window and struck a wall next to a child's crib.
No one was injured during the attacks, police said.
The vandalism occurred at homes on Arlene Way, Charlotte Way, Felicia Avenue and Almond Avenue.
Anyone with information is asked to contact Livermore police at (925) 371-4900.
In the attack on the Livermore officer, two men allegedly attacked him and broke his leg when police attempted to break up a large, drunken gathering.
Police had received multiple 911 calls about the rowdy event on 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 is also asked to call Livermore Police Officer Steve Goard at (925) 294-7531
