VALPARAISO — Police say they are investigating a rash of counterfeit $100 bills that have been used at businesses throughout the city.
The bills in question are "washed" $10 bills and turned into $100 bills, police said.
The $10 bill is bleached and a $100 bill is printed over the bleached bill on a home printer, according to police. The bill's paper typically passes the marker test.
Police encourage local businesses to check the security strip on the bill, which reveals the dollar amount.
Police are seeking help in identifying individuals in surveillance photos from two local businesses.
Anyone with information is encouraged to contact Detective Jason Hamilton at 219-462-2135 or text a tip to TIP411 (219-847-411) and enter “Valpo” in the message field prior to sending your tip.
