KITCHENER — Waterloo Regional Police are warning businesses to be careful when accepting money.

Early Tuesday, between midnight and 12:50 a.m., three restaurant drive-thrus accepted $20 counterfeit bills in U.S. currency.

Police spokesperson Alana Russell said in each incident a four-door black sedan was seen leaving the restaurant.

Anyone with information on the counterfeit cash should call police at 519-653-7700.
