Clark County sheriff’s deputies quickly detained a Wyoming man who they say opened fire inside the Hazel Dell Wal-Mart early Wednesday morning. No one was shot or injured during the incident.

Law enforcement swarmed the Wal-Mart, 9000 N.E. Highway 99, just before 7 a.m. when a 911 caller reported an active shooter at the store, Clark County Sheriff’s Office Sgt. Fred Neiman said.

The man was reportedly firing shots near the Subway restaurant, which is inside the store near the front entrance, Neiman said.

Arriving deputies entered the store and quickly detained the accused gunman, Shaun Michael Sprague, 35, of Gillette, Wyo., without further incident, Neiman said. He was arrested on suspicion of first-degree assault and booked into the Clark County Jail.

After they had Sprague in custody, law enforcement searched the store for potential victims and possible accomplices, but none were located, Neiman said.
