Police locked down several UA buildings Friday evening after a report of a man on campus with a gun.
Police officers take up positions at the Modern Languages Building. A caller who reported seeing a man with guns also said there'd been a shooting in the adjacent Administration Building, but there was no evidence of it.
University of Arizona students mill about outside the Student Union, waiting for news about Friday's incident. Numerous streets were closed to traffic, and about 20 Tucson police cars could be seen on campus.
