Police responded to a report of an armed robbery at 9:30 p.m. Wednesday at a house on East Atwater Avenue occupied by members of Delta Sigma Phi fraternity.
Residents told police four people entered through the unlocked front door before allegedly pointing guns at them and telling them to get on the floor with their hands behind their heads.
The six residents reported that the suspects went through bedrooms and picked up cash, wallets, cellphones, watches and jewelry.
The suspects allegedly hit a homeowner in the head and left a bruise.
The homeowner told police he noticed something abnormal about the gun, so he grabbed it and yelled that it was fake. He told the police the residents began fighting back after realizing that all four guns were likely fake.
During the fight, the residents ripped the ski masks off two of the suspects. One of them was a white man. The other suspect was a black woman who the residents said they knew and who had been at their house before.
The suspects reportedly ran out the door, and one of the residents called the police.
Police are now trying to find the female suspect who the residents identified. The investigation is ongoing.
