The Arkansas City Police Department has been seeing an increase in counterfeit money in local circulation.

Police said in a release that they are predominantly seeing fake $20 bills. These bills all have the same serial number on them and are clearly marked on the bill as “COPY MONEY.”

They are encouraging residents and businesses to the extra time to examine money that is passed during a transaction.

Anyone with information about those responsible for the recent counterfeit money is encouraged to call the Arkansas City Police Department at (620) 441-4444 or (620) 441-6601.

Those wishing to remain anonymous also may contact Cowley County Crime Stoppers, which offers rewards of up to $2,500 for information leading to an arrest, by calling (620) 442-7777 in Arkansas City or (620) 221-7777 in Winfield.
