(PORT HURON) -- Port Huron police say a yearlong federal and local investigation of illegal firearms sales has led to a raid on an unlicensed gun shop and the arrest of its owner. Police say they began the probe after Goldie's Loan and Sales, located in the 1100 block of 10th Street in Port Huron, refused to follow state reporting requirements for sellers of used goods and precious metals. Undercover agents made repeated purchases at the store in an investigation assisted by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives. Police say they raided the store Tuesday morning and seized an assault rifle, seven other long guns, three handguns, gold, silver, cash and illegal drugs. 60-year-old Dennis Eugene McAtamney faces charges of selling firearms without a license. He was transported to Detroit by Federal Officers.
