BIDDEFORD — Biddeford police announced today they have broken up a counterfeit inspection sticker operation and seized computers, printers and materials used in the scheme.

Police became aware in March that a group had been selling fake inspection stickers for between $75 and $100 each and police issued court summonses to 105 people on the charge of using a counterfeit inspection sticker.

The arrest of three men starting on May 12 and culminating Friday on charges of selling fake inspection stickers led officers from Biddeford, Saco and Maine State Police on Friday to conduct a search at 907 Portland Road.

The seizure of equipment led to the arrest of Richard Andrews, 39, of Arundel. Andrews has been charged with aggravated forgery, a felony, as have the three others: Shane Jones, 23, Christopher Perry, 34, and Forrest Mills, 34, all of Biddeford.

Police also have a warrant for a 43-year-old Saco man in connection with the same incident.
