WICHITA, Kan. (AP) — Authorities are investigating after a bank inside the Wichita State University student center was robbed.

A crime alert that the university sent to students, faculty and staff says a man walked into the Commerce Bank in the Rhatigan Student Center around 3 p.m. Thursday. The alert says bank staff members were threatened and that an undetermined amount of money was taken.

The Wichita Eagle reports that a Sedgwick County emergency dispatcher says the man “tossed them a note” over the counter.

The WSU alert said no one saw any weapons. No one was injured.

Authorities are asking anyone with information to come forward.
