April 12 (UPI) -- A student was killed and an officer was injured Monday during a school shooting incident in Knoxville, Tenn., authorities said.
The Knoxville Police Department said in an issued statement that "one male" was pronounced dead at the scene of the 3:15 p.m. incident at Austin-East Magnet High School, while another was detained for questioning.
A Knoxville police officer responding to a call of an armed suspect at the school was hit by gunfire and taken to a local hospital, authorities said.
"There are no other known gunshot victims," the police department said.
David Rausch, director of the Tennesse Bureau of Investigation, said police found the individual in a restroom at the school and ordered him to leave. He refused and fired shots with at least one officer returning fire.
The gunman was identified as a student at the school and died at the scene.
"This wasn't a school shooting, this was an officer-involved shooting inside of a school, much different," said Rausch. "At this point, the student hadn't done anything with the firearm until the officers engaged. It's important to make that distinction."
Knoxville Police Chief Eve Thomas said the injured officer was in surgery and listed in critical condition.
Knoxville Schools Superintendent Bob Thomas said in a tweet that the school building has been secured "and students who were not involved in the incident have been released to their families."
Police earlier reported that a "reunification site" was established at the baseball field behind the school.
Austin-East Magnet High School will be closed on Wednesday and Thursday and will not hold classes online for those days, Knox County Schools wrote on Twitter.
Knoxville Mayor Indya Kincannon said the community must "work together to stop the violence."
The shooting is the latest incident at the high school where three teenagers have died from gun-related violence in recent months.
"We are working together the city, with parents, the school system and community-based organizations," Kincannon said.
