A male teenager was killed on Monday afternoon during a shooting at the Austin-East Magnet High School in Knoxville, Tennessee, the Knoxville Police Department told the Knoxville News Sentinel in an email.

A police officer was also wounded, and is now undergoing surgery after being shot in the hip, a person with knowledge of the matter told Knox News. That source also said one person has been detained in connection with the shooting. Officials have not publicly announced how many people were shot or their conditions.

Austin-East Magnet High School is now secure, Knox County Schools Superintendent Bob Thomas tweeted, and classes have been canceled for the next two days. In the last few months, four Knoxville teens have been shot and killed, including two Austin-East students.
