Officials say three people were wounded when gunfire erupted at a gun show at the North Carolina state fairgrounds.

It happened Saturday at the Dixie Gun and Knife Show, a quarterly event that usually draws thousands of people.

State agriculture department spokesman Brian Long says a 12-gauge shotgun discharged while its owner unzipped its case for a law enforcement officer to check it at a security entrance.

Two bystanders were hit by shotgun pellets and taken to a hospital. A retired deputy sheriff suffered a slight hand injury.

Long says the shotgun's owner, 36-year-old Gary Lynn Wilson of Wilmington, brought the weapon to the show to find a private buyer.

Wake County Sheriff Donnie Harrison says it's too early to know whether Wilson might be charged.

The show shut down early Saturday but will reopen Sunday.
