Police: Pizza perp pulls pistol.
By Lynn Hsieh Reports of a gunman on the loose left some students confused and shaken as police and university officials sent out a series of text messages to students alerting them of the danger.
After a two hour search by police, an “all clear” message was sent to students through the campus alert system.
The suspect has not been found.
A Faculty Student Association (FSA) employee in the SAC cafeteria approached the individual, who police describe as a 5’ 9’’ male between 25 and 28 years of age with a tattoo on his right hand, after it was determine that he was trying to steal food.
President Shirley Strum Kenny told reporters in a press conference "at that point, the perpetrator showed what appeared to be a gun," Kenny said.

Eyewitnesses reported seeing the suspect fleeing the Student Activities Center (SAC) and run towards the back of Harriman Hall between the Old Chemistry buildings at around 1:30 pm.
Mario S., an exchange student, witnessed the event. He and his friends described the suspect as a black male dressed all in black with a long coat and dark boots with a red-green pizza box in his hands.
The security personnel chasing the man yelled “Stop. I won’t touch you,” Mario S. said.
Assistant Chief of Police Douglas Little described the security guard as a "greeter" who works for the Faculty Student Association, "backed off and called police."
Police arrived minutes later.
