Gunfire in a restaurant parking lot sent customers and workers running or cover late Tuesday night.

An employee at the Waffle House on Lawrenceville Highway at Interstate 285 told Channel 2's Darryn Moore he heard two cars collide by the sign outside and then several gunshots.

Antonio McDaniel, a cook at the Waffle House, told investigators he was working the grill when he heard the commotion and dialed 911.

"It was a black car parked sideways and the white van was just ramming it. Guy jumps out of the black car and started letting off rounds," McDaniel said.

Witnesses said the driver of the van drove off. Officers found the van about half a mile down the street with a gunshot wound victim inside.

More said police used coffee cups from the restaurant as evidence markers.

Investigators did not know the man's condition. Witnesses said police arrested the shooter.

Officers are checking to see if mounted surveillance cameras captured the incident.
