CHARLOTTE, N.C. -- Charlotte-Mecklenburg Police is investigating after shots were fired and a car overturned in north Charlotte.

NBC Charlotte received exclusive surveillance video that captured the moments before the shooting. In the video, a Ford Fusion was speeding through a gas station parking lot. Moments later, an older model Mustang was seen following close behind, almost slamming into it.

Earlier on Monday, officers responded to a call of an assault with a deadly weapon near the corner of North Graham Street and Starita Road. A vehicle shot at another vehicle that was driving.

A woman was working when the shots rang out.

"I was over there talking to a customer when I heard a noise coming from outside," said Darlene Alaz, a store clerk. "And I was like I thought somebody got a flat tire, but actually it was a gunshot."

Police are now searching for the subjects involved. Anyone with information is asked to call 704-334-1600.
