A man and a woman were shot inside the building complex that houses CNN’s headquarters in what police described as a “domestic situation.”

The two were arguing when the man pulled out a gun and shot the woman, Atlanta Police Officer James Polite said. He said the man was then shot by a CNN security guard. Their conditions were not immediately released.

CNN reported that the offices of its Internet operations, CNN.com, were immediately evacuated and that a suspect was in custody. Video footage showed police pointing guns at a man lying on the ground inside a building.

An announcement over the building’s public-address system said there had been gunfire “with potential casualties by the escalators” near the main entrance of the building, facing Centennial Olympic Park.

“I heard four or five shots. I really didn’t see it. I got out of there quick,” said Jas Stanford, 27, who had been helping take down a stage in the park that was used for festivities surrounding the final games of the US college basketball championship tournament.

The CNN complex also includes the Omni Hotel, a large atrium and a food court. It is connected to Philips Arena, the home of the National Basketball Association’s Atlanta Hawks.

In the food court, Trina Johnson, 44, of Atlanta, was with her daughter on a family outing.
