One person was killed and another was critically wounded in a shooting at Kentucky State University, the city of Frankfort said Tuesday.

A suspect has been arrested, Gov. Andy Beshear and the city said. Both victims are Kentucky State University students, but the suspect is not, according to the city.

The shooting occurred outside a residence hall on the school's campus, a spokesperson for the university said. The suspect was arrested by university police immediately at the scene of the shooting, the spokesperson said.

Beshear described the shooting as an isolated incident. 

"This was not a mass shooting or a random incident, based on what I've been told," the governor said in a video statement.

The wounded person was taken to a local hospital in critical but stable condition, the city said.

"We will share more information as available. Law enforcement are on scene, and a suspect has been arrested. Let's pray for all those affected," Beshear said earlier on social media.

The Frankfort Police Department said it responded to an "active aggressor" on KSU's campus in Frankfort around 3:35 p.m., adding that the campus is on lockdown until further notice.

A spokesperson for KSU said the university is working on "gathering accurate and complete information."

"Once all information are collected and verified, the University will issue an official statement," the spokesperson said.
