Two more people are in custody following an attack on a pregnant pizza delivery driver in southwest Atlanta, Atlanta police said Thursday.

A boy and a girl, both 16, face multiple charges in connection with the incident, which occurred just before 9 p.m. Wednesday in the 4100 block of Waits Avenue in southwest Atlanta.

According to police, the driver was delivering a pizza to a home when three people approached her from the rear of the residence.

“The victim advised that one of the males was holding a black handgun,” Atlanta police spokesman Officer Jarius Daugherty said in a statement. “At that time, the male with the gun started to strike the victim with the weapon and demanded the keys to her vehicle.”

The woman refused and ran to a neighboring house before the suspects caught up with her and continued their assault, he said.

Dennis Madaris heard the woman’s screams and went outside with his firearm, Daugherty said.

“When I came around the corner here, I saw three people were beating on this lady. One of them had a gun,” Madaris told Channel 2 Action News. “One of them turned around and he had the gun in his hand. I told him, ‘Drop the gun or I will drop you!’ And they threw the gun down and all three of them took off.”

Atlanta police previously detained one man in connection with the crime. He has not been identified.

The teens were captured later on charges of criminal attempt to commit robbery, aggravated assault and obstruction of officers. The boy was also charged with possession of a firearm during the commission of a felony and possession of a controlled substance.

Wednesday’s attack occurred 11 days after a 9-year-old boy lured another female pizza delivery driver to same street. Two men then stole her car at gunpoint.
