After a Bid Night incident in which a partygoer pulled a gun on three security guards hired for the evening, a UA fraternity president said his house will begin checking identification at the door for parties.

Security guards escorted three men out of a Sept. 13 party at the Alpha Gamma Rho house, 638 E. University Blvd., for having a bottle of liquor and for making lewd statements to females.

As the men were escorted out, they became increasingly vocal, threatening partygoers and making racially charged statements.

Once outside, one of the men pulled a gun out of his pants and pointed it at security guards, while he continued to threaten them, reports stated.

Matthew Zubicki, one of the security guards on duty during the evening, described the gun as a black semi-automatic handgun.

Kevin Ward, one of the other security guards, said that the one of the three men told him to "go to hell."

Police responded to the scene after the man suspected of pulling the gun and his friends had left the party, running southbound on North First Avenue.

The police got a description from witnesses and searched the area, but were unable to find the man.

Later in the morning, Tucson Police Department received a call of a reported break-in at a house on 632 E. Fourth St. The suspect matched the description of the individual from the party, and police were able to get a license plate number from the vehicle he fled in.

Reports compiled from witnesses described the subject carrying the gun as approximately 5-foot-4-inch and wearing a blue Hawaiian shirt, a white baseball cap, and blue jeans.

Sean Ryan, president of the fraternity, said no one at the party knew the three men. He added that security at the fraternity had the situation under control.

"I felt like security did its job," he said.

Ryan said that as a result of the event, his fraternity will begin checking IDs at the door during parties.

As of Friday, the University of Arizona Police Department had not found the individual suspected this incident, said Cmdr. Brian Seastone.
