BUIES CREEK - A Campbell University student from Fuquay-Varina has been charged after chemical explosions forced the evacuation of a dorm early Friday at the Buies Creek campus.

No one was injured, and authorities described the episode as a prank.

Thomas Nathan Minor, 19, was charged with possession of weapons on school grounds, the Harnett Sheriff's Office said in a news release.

A second student also was taken into custody, said John Roberson, vice president of marketing and planning at Campbell. The sheriff''s office said additional charges are possible but did not mention a second suspect.

Roberson said three home-made devices "that were little more than big firecrackers" went off about 4:30 a.m. He said the devices were meant to make noise and not do physical harm.

"We just believe it was an ill-thought prank that went awry," Roberson said.
