Atlanta police are investigating an incident late last month in which a driver for the ride-sharing company Uber allegedly pointed a gun at a restaurant’s parking valet and threatened his life.

Channel 2 Action News reported that the Uber driver was outside northwest Atlanta’s JCT Kitchen about 8 p.m. Aug. 30 when he was approached by the valet.

“That employee asked the Uber driver to move forward to park in a designated space, at which time an altercation ensued,” Atlanta police spokesman Ralph Woolfolk told Channel 2. “Subsequently, the Uber drive pulled out a gun and pointed it at the employee and told him he was going to kill him.”

Police have not arrested the driver, who left the scene before officers arrive, but say he could face an aggravated assault case, according to Channel 2.

Uber issued a statement about the incident, but did not say if the driver was still employed with the company.

“Safety is Uber’s #1 priority,” the company said in the statement. “We take reports like this seriously and are treating the matter with the utmost urgency.”
