An off-duty Glendale officer used a Taser on a 14-year-old student during a fight Tuesday morning at Desert Sky Middle School in Glendale.

Officer Justin Collum of Glendale police was working an off-duty job as a school resource officer in uniform at the school on Grovers Avenue near 51st Avenue, said Detective Tara Simonson with the Glendale Police Department.

Two 14-year-old male students were fighting near the football field and Collum told them to stop, a press release said.

When the students did not respond and continued fighting, Collum used his Taser on the �primary aggressor� to prevent injury to the other student, the release said.

The student identified as the aggressor was described in the release as 6 feet 1 inches and 145 pounds. The other student was described as being smaller.

After Collum stopped the fight, the aggressor was taken into custody. Neither student in the fight suffered serious injuries, the release said. Both students were released to their parents.

Charges in the fight were being referred to the Maricopa County Attorney Juvenile Division. Both students could face charges of assault and disorderly conduct, the release said.

According to the release, an internal investigation is being conducted on Collum for the use of force, which is normal practice when a Taser is used.
