25-year-old woman, three juveniles arrested after gang melee caught on video

Merced police say they've arrested a 25-year-old woman and three juveniles involved in an Oct. 21 fistfight caught on video.

The woman, Andrea Olvera, two 15-year-old girls and a 15-year-old boy -- were arrested Thursday for allegedly participating in the fight, reported around 4 p.m. at Rambler Road and College Green Drive, according to Lt. Andre Matthews, police spokesman.

The fight was sparked over a conflict among girls over a boy, combined with gang overtones, Matthews said. When asked how the video was taken and how police got ahold of it, Matthews declined comment.

The video shows two teenage girls being attacked by at least four people. One of those seen kicking a 15-year-old girl was Olvera. The people in the video also yelled their gang affiliation as they dragged, punched and kicked two girls on the ground. Police didn't include audio with the video clip.

The juveniles and the victims attend Merced and Yosemite high schools.

A 15-year-old boy in the video was identified and arrested for robbery. He pushed one of the girls to the ground and stole items from her, while another girl started striking her, Matthew said.

Police also obtained evidence of gang affiliation after serving search warrants at the homes of Olvera and the others.

Olvera was booked into the Merced County Jail on suspicion of assault and battery with gang enhancements, in addition to child endangerment. The teens were booked into juvenile hall on suspicion of assault.
