A meet up between two men turned into a deadly shooting Sunday after one of the men allegedly held up the other, police said.

The shooting happened around 12:30 a.m. outside a Shell gas station on Snapfinger Woods Drive in DeKalb County, according to Channel 2 Action News.

One of the men told police he was kidnapped by a man he “met up with for a sex act” and was forced at gunpoint to withdraw money from several ATMs.

Police told the news station that when the attacker put his gun down, the driver pulled his own gun and shot his attacker once, killing him.

No charges have been filed and police told Channel 2 the killing is being investigated as self defense.
