A metro Atlanta police sergeant accused of pulling a gun on a customer in a McDonalds drive-thru as been arrested.

Forsyth County sheriff's spokesman Courtney Spriggs Wednesday said DeKalb County police Sgt. Scott Biumi has been charged with aggravated assault after authorities say he pointed a gun at a man during an argument on April 9.

Sheriff's officials say surveillance footage from inside the restaurant shows the 48-year-old sergeant step between the man's car and the drive-thru window. Authorities say he pointed the weapon into the car as he leaned into the driver's side window.
