(CNN) -- A suspect is in custody about an hour after one person was shot late Monday morning on the campus of Middle Tennessee State University, a school spokesman said.
Officials called off a lockdown, which had been in effect as SWAT teams and other law enforcement authorities converged on the campus, after the suspect was detained about 12:45 p.m., said the university's media relations director, Tom Tozer. A gun said to have been used in the incident has also been confiscated.
Authorities were alerted at 11:51 a.m. about a shooting in a basic and applied science building located in a cluster of university structures.
"From what I understand, there were two men who got into an argument over by some of our buildings," Tozer said. "One shot the other in the hand, then took off."
The victim, whose condition was not immediately known, was taken to a nearby medical facility. Tozer said he cannot confirm whether those involved were students.
Meanwhile, police began hunting for the shooter on 25,000-student university's campus, in the central Tennessee city of Murfreesboro. Firearms are not allowed on campus, per school policy, according to Tozer.
The spokesman said that officials believe the situation is now under control.
"We are advising people to proceed with caution with normal activities today," Tozer said.
