NEW DETAILS: 3 pedestrians, cop car hit by stolen delivery truck during chase

Three pedestrians were injured after being hit by a vehicle that also struck a cop car during a chase Saturday morning in Clayton County, police said.

The three people, two 17-year-old girls and a 42-year-old woman, were taken to a hospital with broken bones and abrasions, according to Channel 2 Action News. One 17-year-old was also treated for head trauma.

They were hit by a delivery truck stolen earlier that morning from an Auto Zone in Jonesboro, the news station reported. A 16-year-old boy was behind the wheel, Clayton County police spokeswoman Sgt. Ashanti Marbury told Channel 2.

“One of the drivers, who is a delivery driver, left the delivery truck running with the keys in it,” Marbury said. “He forgot an item and had to run back inside.”

When the delivery driver returned to his truck, the 16-year-old was sitting in the driver’s seat and “pretended like he had a weapon,” she said. The driver then backed off.

The theft was reported at 9:30 a.m., setting off a police chase down Mount Zion Boulevard. At one point, she said the teen hit a patrol car and drove the wrong way. He reportedly blew through a red light and hit a truck.

"That actually caused his vehicle to spin out of control and he struck three pedestrians who were standing on the median," she said.

They were flagging down cars to raise money for a local high school, according to Channel 2.

The investigation briefly shut down both Mount Zion Boulevard and Mount Zion Road Saturday afternoon.

Police said the driver, who is not being identified because he is a minor, is expected to face multiple felony charges.
