A gun was discovered inside a Bronx high school Tuesday morning following a fight between students.

The incident happened around 9:10 a.m. in a hallway at Health Opportunities High School in Mott Haven.

A representative from the School Safety Agents union says both students ran out of the school during the fight. One of the boys returned about 10 to 15 minutes later and was searched by school officials.

“The student was found in possession of a loaded 9 mm firearm,” the representative said.

He also said the fight is being investigated as a gang related incident.

Police say there were no injuries, and no arrests made.

Jenna Lyle, a spokesperson for the Department of Education, released a statement about the incident:

“The safety of our students and staff is our top priority, and all students and staff are safe. NYPD safely recovered this item, all safety procedures were followed, and we are working closely with NYPD regarding follow-up actions.”
