FAIRFIELD (KRON) — A high school in Fairfield was placed on lockdown briefly on Thursday morning after two students, one of them with a replica handgun, got into a fight, according to police.

The fight happened on the campus of Sem Yeto High School, located at 205 E. Atlantic Avenue, at around 9:20 a.m., police said.

A staff member broke up the fight but informed the school’s resource officer that one of the students pointed a weapon at the other then threw the gun onto a nearby roof, police said.

The Fairfield Fire Department responded with a ladder and officers recovered an airsoft gun that resembled a firearm from the roof, police said.

The incident locked down the school for 35 minutes.

Police arrested Carlos Rios-Morales, 18, of Fairfield, for brandishing a replica firearm, creating a campus disruption and possession of marijuana on a school campus.

Police used the incident to remind parents that carrying airsoft guns that resemble real firearms is dangerous.

Police also said they will pay a $200 reward for information that leads to the recovery of an illegally possessed firearm on a Fairfield school campus.Bay City News contributed to this report
