Two more cases of counterfeit bills have surfaced in Austin, which adds to the concern in the past weeks.

According to the Austin police report, Wells Fargo Bank Tuesday found a counterfeit $20 from Radio Shack’s deposit and a fake $10 and $20 from Apollo Suprette’s deposit. Both bills would have been passed sometime on Monday. Police will look at available video surveillance and attempt to identify who passed the bills.

In the past weeks, three fake $20s and one $10 were discovered, as well.

Other communities seeing counterfeit bills include Byron and Winona. Police have no suspects.
