Police say Randall O'Bryan, Wesley Hawkins and John Vanover broke a window at Del's Diner to enter through a door.
They allegedly took several items, including the cash register. The investigation led to the three arrests on burglary charges.
Police say when Vanover was arrested, he admitted to several other burglaries and thefts in the west part of the county.
Those items taken were mostly farm equipment to be sold for scrap metal.
