MANDAN, N.D. — A Walmart here was evacuated Friday, Aug. 9, after a person confronted a vendor, pulled a knife and cut the vendor near one ear.

The male vendor was not seriously hurt. He was checked by paramedics at the scene, Mandan Deputy Police Chief Lori Flaten said. Authorities described the cut as "very minor."

Officers responded about 11:30 a.m. and searched the building for the attacker. Police early in the afternoon were still looking for him.

The attack appeared to be random. The vendor did not know the attacker, according to Flaten.

Police were trying to identify the man through surveillance video. They released pictures of him but cautioned people not to approach him if spotted, but to call police.

They later identified a "person of interest" wanted for questioning -- Hilario Flores, 24, described as 5 feet 5 inches tall, weighing 140 pounds, with brown hair and brown eyes. Authorities said he could be in a grey Honda or Toyota car. Flaten said police were not sure if Flores is the same person depicted in the surveillance video.

It was the second Walmart in the region to be evacuated in as many days. A Dilworth, Minn., location was evacuated on Thursday after a 911 caller reported a man had a gun inside the store.

This story has been updated to correct where the vendor was cut.
