DALLAS (CBSDFW.COM) — A man was taken to a hospital in critical condition after a store clerk shot him through his car window Friday night.

Officers responded to a shooting at the Peachtree Food Mart on Walnut Hill Lane around 11:30 p.m., according to the Dallas Police Department. Police conducted a preliminary investigation and arrested Zafar Ali Raza, a store employee, in the shooting. Raza was charged with aggravated assault with a deadly weapon.

Before the victim was shot, he was assaulted by several people in front of his children, who were inside his car.

Police say the victim’s SUV, with an attached trailer, and the disabled U-Haul his wife was driving were blocking both sides of gas pumps in the store parking lot. Raza approached the man, asked him to move the vehicles and then went back into the store.

Afterward, the victim got into a “disturbance” with several unknown people in the parking lot who were upset with him for blocking the gas pumps, police say. The people then assaulted him, prompting Raza to return to the parking lot with a handgun.

The man got into the SUV and tried to drive away, but the 50-year-old shot him once through the driver-side window, according to police.

Raza is currently in Dallas County Jail. Dallas Fire Rescue took the victim to Texas Health Presbyterian Hospital in critical condition.

No other injuries have been reported, and the investigation is ongoing.
