Washington, Sep 28 (DPA) The University of Texas in Austin was on lockdown Tuesday morning after shots were fired in the university library.

The shooter was dead from an apparent self-inflicted gunshot wound on the sixth floor of the Perry-Castaneda Library, the university said in a statement.

Police told reporters the man was wearing all black and carrying an AK-47 rifle.

There were no reports of other injuries, police said.

Police were working to secure the campus and rule out unsubstantiated reports of a possible second gunman before allowing students to leave the buildings where they had sought shelter, said university police chief Robert Dawson.

The university located in Texas state capital, Austin, is among the largest in the US with some 50,000 students. In 1966, a gunman firing shots from a tower in the central part of campus killed 16 students.
