A student at an American university in Northern Illinois was shot at early morning on Friday, forcing the authorities to shut down the campus here briefly.
The wounded student at Northern Illinois University was taken to a hospital and the suspect is in custody, said the University, where just over two years ago a disturbed student shot 21 people.
"NIU Public Safety officials are stating that the event appears to be an isolated incident between two individuals, and that the alleged assailant is in police custody," the university said in a campus alert posted on its website.
The shooting occurred around 3:30 am and the campus was shut down. But later, the campus was re-opened and the university said classes would be held as scheduled.
Last week, the university had observed the second anniversary of a mass shooting on campus in which 27-year-old graduate student Steven Kazmierczak had killed five students in a lecture hall and injured 19 others.
Kazmierczak had then killed himself on February 14, 2008.
