HAMILTON, N.Y. (AP) — A private liberal arts college in New York is warning students of a possible “armed person” on campus.

Colgate University in Hamilton issued an alert on Twitter Monday night saying there was an armed person at the Coop and that law enforcement was searching the building. The school also told students to “find a safe space and remain indoors.”

Campus safety officials later reported that no shots had been fired but the situation was still under investigation.

The university’s website says the Coop is a center for student activities including dining.

The school is located southeast of Syracuse.
