Atlanta police have a "person of interest" in custody after a man was killed at his own birthday party.

The shooting happened Wednesday night at an AirBNB on the southeast side of the city, police told FOX 5 Atlanta. The victim has only been described as a man in his 20s.

Police say an altercation broke out around 11:45 p.m. at what was not a large party. The fight began inside the home before spilling outside. The victim was shot once and taken to a hospital, where he died. 

Few details are being released at this time, and police would not say where on his body the victim was shot. A FOX 5 Atlanta reporter tells Fox News a number of loved ones showed up at the scene, visibly upset over what happened.
