WAUKESHA, Wis. (AP) – Waukesha police say they’ve arrested a man in connection with a lockdown at Carroll University.  Students were asked to stay inside university buildings after two students reported seeing a man with a gun on campus Tuesday. Police Capt. Ron Oremus says investigators learned the man’s identity and contacted him at his apartment nearby where he was arrested. Oremus says a non-lethal air gun was confiscated from the man’s residence.  The university sent text alerts and emails to students and staff when public safety officers received the reports of a gunman on campus. Several public schools were also locked down in the area as a precaution.   Oremus says that in today’s climate police have to take such reports seriously. He says police are looking into whether the man did anything illegal, given the gun was non-lethal.
