A man who caused a lockdown Tuesday at Carroll University in Waukesha after walking around the campus carrying an airsoft gun was ticketed for disorderly conduct Wednesday, the Milwaukee Journal Sentinel reported.

The campus was placed under lockdown Tuesday morning at 10:39 a.m. after reports surfaced of a gunman on the campus. Local police, an armored vehicle and the FBI responded to the supposed threat.

The lockdown ended shortly after noon, however, when Michael Wiedeman, 50, of Waukesha was taken into custody. It was later revealed  in a Carroll press release that the man was carrying a non-lethal airsoft gun.

Wiedeman will face a $303 municipal ticket, Waukesha police Capt. Ron Oremus told the Journal Sentinel, and the case will be closed.

The university resumed normal operations that afternoon.

“At no time were Carroll students, staff or faculty in danger,” the university said yesterday in an updated statement.
