LITTLE ROCK, Ark. (AP) — An apparent stranger shot and injured the bride, groom and two other people at an outdoor wedding in rural Arkansas, then was arrested after being chased by outraged guests, a sheriff's official said Sunday.

The wedding was just ending Saturday when the man approached with a 9 mm pistol and opened fire, Pope County sheriff's Lt. Aaron DuVall said. No one else was hurt.

About 50 people, including children, had attended the ceremony along Piney Creek north of Dover at a spot the lieutenant said was popular for picnicking and swimming. Dover is 64 miles northwest of Little Rock.

The gunman "was not associated with the wedding at all," DuVall said.
