A man opened fire Monday morning outside an Amazon facility in Columbus, sparking a brief standoff with police before taking his own life, authorities said.

The Columbus Police Department said officers responded around 4:47 a.m. to reports of an active shooter in the 5800 block of Osceola Court. Police said the man fired multiple shots into the front of the building from outside before walking a short distance away, where officers confronted him.

That's when investigators say the man brandished a firearm, sparking a brief standoff. The incident ended when the suspect allegedly shot himself and died.

Police did not say whether the man had any connection to the Amazon facility.

No other injuries were reported. The department's Violent Crimes Unit is leading the investigation.

Columbus is located about 110 miles south of Atlanta. 

The investigation remains ongoing.
