Fresno Police Chief Jerry Dyer announced the arrests on Tuesday. According to the Fresno Bee, he identified the suspects as 17 and 16-year-old Norteno gang members.
Police have said the teens were armed with a handgun and a sawed-off shotgun when they confronted Edison High School teacher Steven Guerrero in a classroom around 7 p.m. Thursday.
Guerrero allowed the group to take a computer but then fought back after one of the teens allegedly struck him with a free weight. He was shot in the stomach and leg, but survived.
Dyer said the shooter was a student at Edison and has confessed.
