Last weekend, Young Chop got locked up in Atlanta.

Now we know why.

According to a Gwinnett County, Georgia police report, on Sunday Chop got in an Uber to go search for 21 Savage at an apartment complex he didn't know the address to.  When he eventually figured it out he had the driver drop him at a residence, and then quickly returned to the car.  Soon after that, Chop got in a heated argument with an unknown man, during which Chop brandished a semiautomatic black handgun. 

Chop's Uber was then pursued by a four-door sedan that began shooting, hitting the driver's rear door, the driver's side rear panel and shattering the driver side rear door window.

The Uber driver -- who must have really wanted five stars -- then pursued the sedan at Chop's request.  However, they were not able to catch up or get the car's license plate.

Chop Livestreamed much of the incident and was arrested for reckless conduct. He bailed out the next day.
