Three Lebanon High School students were arrested Friday after authorities say they were seen on campus Friday passing around a stolen handgun. The sight of the boys with the gun led to police response and temporarily not allowing anyone in or out of all schools in the town.

No shots were fired and no one was injured, according Lt. Scott Bressler, a Lebanon police spokesman. The three boys range in ages from 14 to 16 and have been booked into the Linn-Benton Juvenile Detention Center on suspicion of unlawful possession of a firearm, first-degree disorderly conduct and hindering prosecution

The firearm was reported stolen from a resident's home a week ago, Bressler said. He didn't know if any of the three teens were involved in the alleged theft.

The high school was placed on lockdown around 9:40 a.m. after school officials learned someone was seen on campus with a gun. Students and staff locked themselves in classrooms, turned off the lights, closed the blinds and stayed silent, according to the school district.

Lebanon police responded to the school along with other law enforcement agencies including members of Oregon State Police, the Linn County Sheriff's Office and the Bureau of Alcohol, Tobacco, Firearms and Explosives, authorities said.

Other schools in the area were placed on lockout as a precaution, the school district said.

Around 11 a.m., police detained one of the teen boys off campus near the high school, Bressler said. The other two boys were taken into custody sometime after.

Investigators found the stolen gun unloaded in a home. Bressler said he didn't know whose home the gun was found in.

The case remains under investigation.

The shooting threat at Lebanon High School occurred on the same day a Houston-area teen opened fire at his high school, killing 10 people and wounding at least 10 others. That male student was arrested.
