Police in Salt Lake City arrested a juvenile in possession of a firearm at a Salt Lake City school on Wednesday.

According to the Salt Lake City Tribune, a student had seen another student with a firearm in a bathroom and reported it to school administrators, who then summoned police.

The arrest took place without incident, but the school was briefly placed on lockdown as police searched hallways and classrooms for the student and the firearm.

The name of the alleged gunman has not been released because he is a juvenile.
