DURHAM, N.C. — One person was killed in a police shooting at a Durham convenience store early Wednesday morning.

Durham police say the shooting happened at the Circle K on N.C. Highway 54 near Old Fayetteville Road.

According to Durham Police Chief Patrice Andrews, officers were called to the store regarding a “suicide in progress.” Police say the door was locked when they arrived, and someone was violently attacking the store clerk inside the store with a sharp object.

This is the third police shooting in North Carolina in several days, following a shooting in Raleigh Tuesday and in Fayetteville Saturday.

Police forced their way inside and fired shots, Andrews said, killing the person.

“We do not know how many shots were fired,” Andrews said. “We do not know where the assailant was struck.”

The clerk suffered serious injuries from the attack, police say.

Officers involved were treated for minor injuries.

The SBI is assisting in the investigation.

Names will be released after the family of the person killed has been notified.
