No one was hit by gunfire and order had been restored late this afternoon. The campus was closed to outsiders but students with university IDs would be allowed to walk around campus in small groups, police said.

Three students have been arrested on disorderly conduct charges. The suspected shooter was still at large, GSU Police Chief Jefferson Walker said.

Two people were slightly injured in fights that followed the shooting.

Law enforcement converged on the Lincoln Parish campus early this afternoon and restored order. SWAT teams with K9s went building to building.

The campus will be closed to outsiders until Saturday but students with a university ID will be allowed to come and go tonight in groups no larger than three, Walker said.

University of Louisiana System spokeswoman Jackie Tisdell said students and others were fighting in the campus dining hall and two shots were fired.

Fights had broken out on campus before and after that one, police said.

Law officers sent to restore order said they dealt with a very large and unruly crowd.

The fight that led to gunshots at 11 a.m. was a carryover from two off-campus fights the night before during the annual SpringFest and it carried over to campus today, police and the university newspaper said.

State troopers, Lincoln Parish sheriff's deputies, and Grambling and Ruston police were assisting university police deal with the situation.
