A man trying to pay his traffic fines found himself in even deeper trouble when he slapped a counterfeit $20 bill on the counter at Fort Worth Municipal Court.

A marshal escorted the man to a teller Wednesday to pay $70 in fees, according to a Fort Worth police report. The teller performed a routine ink test on the bill that suggested it was a fake.

Upon closer examination, the bill was "soft in texture" and "runny in nature," the report stated.

The teller handed the bill to the marshal, who hauled the suspect back to his office and notified police. The suspect was arrested for his traffic warrants.

It wasn’t clear whether he knew he had a fake bill. Charges are pending while police investigate, the report said. — Alex Branch
