(USA TODAY) -- One student was seriously wounded Monday afternoon at Paine College in the second shooting in less than 24 hours at the campus in Augusta, Ga.
An unidentified 21-year-old student was taken into custody about two hours after the victim was shot in the head inside a dormitory, the Richmond County Sheriff's Office and the campus police said at an evening news conference, WXIA-TV reported.
The victim's wound was described as life-threatening; earlier, sheriff's deputies had said the wound was not life-threatening.
The shooting apparently followed an argument between the two students in Haygood Hall. The suspect was found inside the dorm about two hours after the attack and taken into custody. He had not been identified or charged by Monday night, the sheriff's office and the campus police said in a joint statement.
A senior college administrator did not respond to a USA TODAY request for comment and additional information.
Sunday afternoon, two students suffered minor injuries after a pair of gunmen fired shots into Gray Hall, another men's dormitory. The school said the gunmen were not students.
Officials said there was no immediate information that linked the shootings.
Sgt. Michael McDaniel said earlier Monday that one "person of interest" was in protective custody and being questioned in connection with the 1 p.m. shooting inside an unidentified campus building.
The college was locked down for about five hours but remained closed to the public Monday night. Classes are set to resume Tuesday; Wednesday is the final day of spring classes.
Several nearby public schools and the Georgia Regents University campus and medical center were temporarily locked down.
In a tweet, the college said: "The Paine College Community is saddened by the turn of events and ask that everyone keep Paine in their thoughts and prayers."
Paine College, a historically black school founded in 1882, has about 800 students. Augusta is about 140 miles east of Atlanta.
