A Red Bluff Police School Resource Officer targeting gang activity just started at his new post this week and has already been busy. At about 1 O'clock Wednesday afternoon, several students at Vista Preparatory Academy reported that a group of four older juveniles came onto the campus and challenged several students to fight. The intruders claimed to be gang members. They were wearing gang attire and flashing gang signs. After conferring with the school resource officer at Red Bluff High, the gang members were identified as being students from there. Two of them had apparently confronted a Vista student the previous day and attacked him because of his apparent affiliation with another gang. A 14-year-old and a 16-year-old were arrested.
