A Harlan County man was arrested Sunday after deputies say he robbed a retail store, then assaulted a law enforcement officer. Investigators say Adam Caldwell went into the Family Dollar in Bledsoe Sunday night at closing time, armed with a tire iron. He went to the safe, which was open while employees prepared to store the day’s earnings, swiped some cash. Deputies tracked Caldwell down at his home, and he punched an officer as they tried cuffing him. Deputies used a taser to help take him into custody.
