One man was killed and another was injured after gunfire erupted just minutes apart at two northwest Atlanta locations Thursday afternoon, police said.

Officers were first called to an apartment complex in the 300 block of Skipper Place at 12:14 p.m. and found a man fatally shot inside a home, police said in a news release. A “person of interest” was detained at the scene, according to authorities. Investigators are working to determine what led up to the shooting.

A few seconds later, officers were called to the 500 block of Norfolk Street at 12:15 p.m. and found a man who had been shot by another man after a dispute, police said. The victim was taken to a hospital. His condition was not released, but authorities said he was alert.

“Both the victim and suspect are known acquaintances,” police said in a news release. “Investigators are working to determine the circumstances surrounding the incident.”

Authorities did not say if the gunman had been arrested.
