ATLANTA — Atlanta police are investigating a shooting on 400 Merritts Ave. on Thursday near Central Park in the Old Fourth Ward that left three people injured.

A man inside a building that is serving as a warming center became upset with people inside and pulled out a gun, opening fire.

Two victims were injured in the incident, including a bystander who was hit. Both were rushed to the hospital. The current extent of their injuries are unknown.

“One individual sustained approximately four to five gunshot wounds,” reported Major Peter Malecki. “A second individual sustained multiple, perhaps two gunshot injuries to the lower extremities.”

The shooter, identified as 37-year-old Antonio Wooten, is in custody. Police say Wooten was not shot, but he fell and broke his arm.

There is no word on a motive.

The GBI is investigating the shooting. Once the investigation is complete, the case will be given to the Fulton County District Attorney’s Office for review.
