A lock-down at Florida Atlantic University was lifted Wednesday after authorities found a suspect in an early morning campus shooting, officials said.

Two shots were fired shortly after 1 a.m. at a party in the student apartments on the Boca Raton campus, FAU Police Chief Charles Lowe said. One non-student was slightly injured, but it was not clear if that person was hit by a bullet, officials said.

Exams were canceled and students were told to stay in their dormitories as authorities searched the campus Wednesday morning.

Hours after the shooting, the suspect was found at an off-campus location, according to the school. The campus was to remain closed Wednesday and reopen for classes Thursday. Authorities have not said whether the unidentified male suspect is a student.

Soon after the shooting, sirens, mass e-mails and other announcements over the school's public address system notified students of an emergency and warned them to remain indoors.

The alert system was installed just 60 days ago and had not been fully tested.

"It seemed to work," said FAU President Frank Brogan.

Brogan said fewer people were on campus than usual because it is FAU's finals week.

Guns are not permitted at FAU.
