More instances of counterfeit bills passed in Hays have been reported to the Hays Police Department.

On Friday, the Hays Police Department received reports of fake $100 bills turning up recently at Radio Shack, Westlake Ace Hardware and Hastings.

Investigator Jeff Ridgeway is one of the HPD officers working on these and other recent counterfeit money cases.

“There are numerous security features built into U-S paper currency,” says Ridgeway, “but an alert store clerk is also important:”

Security features on bills printed by the U-S treasury include color shifting ink, watermarks, security threads and micro-printing.
