LENOX -- When the manager at the downtown Alta Restaurant accepted a $100 bill from a customer for a $6 container of takeout soup on Monday evening, little did he know he had been handed funny money.

But after it was deposited at TD Bank in Pittsfield, the eatery was notified that the bill was counterfeit.

According to local police, who posted an alert on the department's Facebook page, the suspect is a white male, about 5-foot-7 or 5-foot-8, in his 20s and unshaven.

Police urged restaurant and business owners to check any $100 bills prior to a transaction, especially if the purchase is for a small amount. As of Wednesday morning, no similar incidents had been reported, police said.

Merchants were notified by the Lenox Chamber of Commerce to be on the lookout for fraudulent currency. Anyone with information is asked to call Lenox Police at (413) 637-2346. Officer William Fuore is handling the investigation.
