DURHAM, N.C. (WNCN) – A $5,000 reward is being offered after Durham County deputies in an unmarked car were shot at Saturday night, the sheriff’s office said Monday.

Two on-duty officers were in the area of Keystone Place and Dearborn Drive around 9:30 p.m. Saturday. They were working “an active and ongoing investigation,” the Durham County Sheriff’s Office said in a news release.

While deputies were watching the area, at least two men fired multiple shots at them. The unmarked vehicle and nearby residences, that were occupied, were struck. No one was injured, deputies said.

“This gun violence cannot go on and has to stop,” Durham County Sheriff Clarence F. Birkhead said. “Innocent people who were sitting in their homes and enjoying a Saturday evening with family could have been seriously injured or killed.”

Later Monday afternoon, deputies announced a $5,000 reward for information leading to an identification and arrest in the incident.

The sheriff’s office said it is investigating the incident. The suspects have not been identified and are at large.

Anyone with information about the incident is asked to call the Durham County Sheriff’s Office at 919-560-0900 or the Criminal Investigations Division at 919-560-0880. The public can also call Crimestoppers at 919-683-1200 with information and can remain anonymous.
