A parking lot shootout outside of a 7-Eleven convenience store and a Jack in the Box restaurant sent customers scrambling for safety Wednesday evening.
The shooting, which occurred at around 9:20 p.m., started outside the convenience store on Towne Avenue and carried over to the Jack in the Box next door, according to the Pomona Police Department.
A group of male suspects in two cars started firing at passengers inside of a gold Pontiac, police said.
Someone started firing round after round into the fast food restaurant. The windows of the Jack in the Box were riddled with bullets.
One witness told NBC4 that over 20 rounds were fired.
During the chaos, one victim drove away, shearing a fire hydrant.
Darshonna Brown was sitting in her car at the restaurant's drive-thru when she heard the gunshots.
"I'm telling the girl who's taking my order, 'Do you hear that?' and she's like, 'Yeah!' and then she took off running -- she left me at the drive-thru!" she said.
Nobody was hurt inside the restaurant, but moments later at a nearby hospital police received word that a victim involved was being treated for a gunshot wound to the leg.
That person suffered non-life threatening injuries, police said.
Police are looking for a group of male suspects in a grey or silver Chevrolet Monte Carlo and a gold Pontiac.
Authorities are hoping that surveillance video can help them piece together the shooting.
