5 adults attack Dublin High School student in locker room

DUBLIN, Calif. - Police in Dublin are investigating two controversial incidents at Dublin High School, including an attack on a student.

The Bay Area News Group first reported that five adults went into the boys' locker room last week and attacked a teen. 

In a letter sent to families obtained by KTVU, Principal Maureen Byrne said that the school's football player and the coach were able to stop the attack.

No motive was revealed and the circumstances of what would prompt the adults to assault the teen were not explained as "this is an active investigation," Byrne said. 

She did not say how old the adults are or what their connection is to the school. 

She said that much of what transpired was captured on video and the police have identified a number of suspects. 

"We are outraged that this happened on our campus," Byrne said in her written message. "School must be a place where all feel safe and supportive."

She said that until further notice, the hallways facing the parking lot will stay locked and students will need to enter through the doors facing the practice field.

Dublin High was also briefly locked down a week ago, due to a phony report that there was a fight on campus involving a deadly weapon.
