Wallace said officers responding to a report of a burglary noticed movement on top of and inside the building, and soon apprehended two suspects.

She said a third suspect inside the business fired on officers, who returned fire, but no one was hit by the gunshots. She said a fourth suspect came out of the business with his hands up.

The store is about 18 miles northwest of downtown Atlanta.

Wallace said shortly before 8 a.m. Tuesday that police were using an armored police vehicle to make entry into the business and make sure there was no one else inside.

Wallace told FOX 5 that as the scene progressed, someone from inside the gun shop began firing and that's when police fired back.

"As far as we know, no one was struck and that third suspect has been taken into custody," she said.

Wallace said she didn't know exactly how the report was received by police, but she said there were no signs of any type of ambush or attempt to lure officers to the store. Police nationwide have been on high alert in the wake of recent killings of police officers in Dallas and Baton Rouge, Louisiana.

Video from a television news helicopter showed officers taking cover behind police cars outside the gun store.

"There are several officers, and our response to anything here lately has been that way," Wallace said. "We want to make sure the business is secure, but also the surroundings are secure for our safety."
