Redlands police say the two 7-foot cow costumes created for the Chick-fil-A chain were nabbed in separate restaurant burglaries.
The costumes turned up for sale for $350 apiece on Craigslist on Oct. 30.
An undercover officer arranged to buy the bovine attire in time for Halloween. When the seller produced the black-and-white outfits, he was arrested.
Forty-three-year-old Robert Michael Trytten, of Riverside, is being held for suspicion of possession of stolen property on $275,000 bail.
The costumes were valued by the restaurant at $2,800 apiece.
Police also recovered a pop-up canopy stolen from the restaurant. All the property was returned to Chick-fil-A.
