Lopez told ABC 11 he was about to make a left in his car onto South Roxboro Street Thursday when he heard a sound like a car backfiring.
Instead, he realized it was a van and a car headed towards downtown on Roxboro and there was gunfire between them.
The van turned onto the street where Lopez was and fired at his car. The bullet hit the upper part of his windshield on the passenger side.
Lopez was not hurt.
"A lot of things just happen instinctively and I just did what I had to do," Lopez said. "I encountered a situation where there was a vehicle the individual was firing out the vehicle."
Lopez chased the car about a block and a half.
"At that time I saw that he was directly firing at me then continued - subsequent to that, I came back to the scene figuring it could be someone hurt," said Lopez.
The other car stopped on Roxboro Street and the person inside was found to have been shot in the back. He was taken to the hospital for treatment. The man is recovering.
Police are still looking for the van that fired on Lopez. The chief says it was a one in a million event.
"This truly an unusual situation. I think the young man who fired at me had better odds at winning lotto than encountering the chief of police during a shoot out," said Lopez.
