Authorities say they've arrested three people following the robbery of a mid-Michigan gun shop that left its owner with severe head injuries.
The robbery happened Monday at Guns and Stuff in Gladwin County's Sage Township, 90 miles north of Lansing.
The sheriff's department says two arrests were made Wednesday followed by a third arrest that night. The department says authorities found evidence related to the robbery, as well as several stolen handguns.
Names of those arrested weren't immediately released Thursday. They were in the Gladwin County jail Thursday awaiting arraignment Thursday or Friday.
The U.S. Department of Alcohol, Tobacco, Firearms and Explosives is aiding the probe.
Owner Richard Robinette was critically injured. Hurley Medical Center in Flint listed his condition as serious Thursday.
