(Fond du Lac) The Fond du Lac Police Department says it has received several reports of fraudulent bank account withdrawals, that may be due to credit card skimming. Both the city and the Fond du Lac County Sheriff’s Department have fielded several reports of unauthorized A-T-M withdrawals from victim’s bank accounts last weekend. Investigators believe accounts may have been affected over the past two weeks. Officers are looking for persons of interests captured on surveillance video. They were last seen driving a green Volkswagen four-door sedan with no front plate.
