TUCSON, Ariz. (AP) — Police converged on the University of Arizona campus on Friday evening after receiving a report of a man with a gun.
A text alert was sent to students and staff at 5:07 p.m. saying police had received a report of a man with a rifle inside the Administration Building.
Authorities and school officials said there was no immediate sign of a gunman and no report of any shots fired.
"We are still assessing the situation," University of Arizona police Officer Joe Bermudez said. "We have patrol units on campus and we're working with Tucson police."
The Administration Building and some surrounding buildings near the campus mall were evacuated and students and staff were being told to avoid the area.
KOLD-TV reported that streets leading to the Administration Building were blocked off and dozens of police officers — some wearing armored vests — were seen on campus with a helicopter hovering overhead.
Campus police didn't immediately release any information on the search for the reported armed man.
A shooting at the University of Arizona's nursing school in October 2002 left three professors dead before the gunman killed himself.
