A shooting at a Knoxville high school on Monday left a student dead and an officer injured.

Police officers responded to reports of a potentially armed individual at Austin-East Magnet High School around 3:15 p.m. local time on Monday, Tennessee Bureau of Investigations (TBI) Director David Rausch said during a news conference, according to CNN.

Officers found the student in the school's restroom, and they ordered him out. He refused and after he fired shots, at least one officer returned fire, Rausch said.

The gunman, who was identified as a student at the school, died at the scene, Rausch said. Authorities said they are not releasing the student's name at this time.

A Knoxville officer was injured in the incident and taken to UT Medical Center, police said. Knoxville Police Chief Eve Thomas said the injured officer is in surgery and listed in serious condition.

The school was on lockdown at one point, before police set up a "reunification site" for parents and guardians to pick up their children.

The Tennessee Bureau of Investigation will lead an investigation into the "officer-involved shooting," the police department said in a statement.
