(CNN) -- The University of Texas at Austin was under a lockdown Tuesday morning after a suspected gunman wielding an AK-47 fired shots and then turned the gun on himself inside a campus library.
The gunman died, said Robert Dahlstrom, chief of staff in the Austin Police Department. No one else was injured.
Police were searching for a possible second suspect and checking campus buildings for possible explosives left behind, said Austin Police Chief Art Acevedo.
The university was closed at mid-morning and all classes for the day were cancelled as law enforcement teams descended on campus.
An ambulance was seen just before 9 a.m. in front of the Perry-Castaneda library, CNN affiliate KXAN reported. SWAT teams, armored vehicles and helicopters surrounded the campus.
