FAIRFIELD — A cop in line at a grocery store Oct. 28 thought the man in front of him was acting very nervous while trying to buy some gift cards using a credit card.

It turned out the credit card, which was rejected several times, was fake, and the officer ended up taking Michael K. Mills, 24, into custody.

The officer followed Mills into the parking lot of ShopRite, 1975 Black Rock Turnpike, asking him several times to stop. Initially, Mills did not stop, saying he did not do anything wrong. He eventually stopped and gave the officer the credit card in question. The card, according to the report, did not look real, with the numbers and letters off center. While being questioned, Mills’ phone keep ringing, and when he finally took the call, the officer could hear the caller tell Mills he would have to find his own ride back to Brooklyn.

Police found five fraudulent credit cards in Mills’ possession. He had receipts from World of Beverages in Norwalk for $500 worth of gift cards and another one from TJ Maxx in Fairfield for $100.

Mills, who lives in Brooklyn, N.Y., was charged with five counts of third-degree forgery, and one count each of criminal attempt at sixth-degree larceny and illegal use of a credit card. He was held in lieu of $10,000 bond and is scheduled to appear in state Superior Court in Bridgeport on Nov. 14.
