A South Jersey pizza shop owner is facing fraud and forgery charges for allegedly overcharging customers' gift cards and credit cards over a months-long period.

Winslow Township police said detectives began investigating after receiving multiple complaints that they had been overcharged at Bella Pizza II, located at 410 Williamstown Road in Sicklerville.

Investigators made several purchases from the restaurant using prepaid gift cards, police said, and those cards were overcharged for the purchases on multiple days.

Officers executed a search warrant at the pizza shop and reviewed credit card receipts and documents from the business. Police determined that more than 30 cards were overbilled, authorities said.

Police said 21-year-old Henry Fernandez Jr., Bella Pizza II's owner, was being charged with several counts of credit card fraud and forgery.

Police said in a statement that Fernandez, of Glassboro, has been overcharging customers "on a daily basis" for about four months.

Investigators believe there may be more victims. Anyone who believes they were overbilled can contact police at 609-567-0700, ext. 1195.

Officials are urging people to regularly check their credit card receipts and bills for fraudulent charges.
