Gwinnett County police are trying to find a driver they say backed into a woman at a gas station and drove off.

The woman suffered serious injuries, the police department said in a statement Monday.

The collision happened shortly after 8 p.m. Thursday at a BP at 325 Harbins Road in Dacula, police said. The driver walked around the gas station, used the ATM and shopped. He then walked out of the store, but did not leave right away, police said.

The woman was putting air in the tires on the passenger side of her car, police said.

The man started backing out of the parking space and paused for a moment, officials said. He then continued reversing out of the space “at a high rate of speed” and slammed into the woman and her car, police said.

He sped away from the scene and headed north on Harbins Road, officials said. Police said he did not return to the scene and did not call for help.

The woman’s collarbone was broken in four places and she underwent surgery Monday, Channel 2 Action News reported. She also needed stitches in her head.

Gwinnett police describe the driver as a heavy-set man in his 20s who was wearing a black and white hat, gray Georgia Bulldogs T-shirt, black shorts and New Balance tennis shoes. Officials said his car is a silver Ford SUV and has a UGA sticker in the lower right corner of the rear window.

Anyone with information is asked to call Gwinnett investigators at 678-442-5626.
