Police in the southeast Kansas town of Rose Hill say someone is trying to use fake money at the town’s businesses.

Police said Monday that at least three businesses have recently reported people using fake cash to pay for items.

In one case, a clerk at the Rose Hill Apple Market grocery store noticed the $20 bills someone was using to obtain a $300 money order were counterfeit. The clerk refused to take the money and called police.

KAKE-TV reports fake money also was used at other businesses, including a Sonic restaurant and Casey’s General Store.

No one has been arrested.
