The caller said a man was inside the admin building with a gun strapped to his chest, carrying a rifle. The caller went on to say there was a shooting there. No gunshots were heard and police did not find anyone injured.
The most recent UAlert sent at 9:09 p.m. reads, "UAPD has cleared the Admin Bldg. No one was [found], no injuries or signs of a shooting. The Stu Union IS OPEN. No campus restrictions All clear."
Earlier today, an alert was sent to subscribers of UAlert which read, "Man with a gun Report of a man w/ a rifle in the Administration Bldg. UAPD on scene. Stay away from the area."
As of 6 p.m., the Admin building was evacuated through the second floor lobby doors. UAPD were in the building.

No injuries have been reported. Students said they felt safe but overwhelmed.
There were between 20 and 30 police cars in the area and a helicopter overhead.
UA sophomore Devin Pate said she was on the UA mall, about to walk past the Admin building when one of her friends got the UAlerts.
"A cop ran past us with a rifle in his hands and said, 'Get down! Run!' so we ran down into the ILC because it was right next door and locked ourselves in a classroom first and then a bathroom for 20 minutes [while] on the phone with the cops," Pate said. "When we walked out of the door, we heard a cop scream 'he's not in the building.'"
Pate said she will not put herself in an enclosed area like that again.
