Suffolk County police ask the public's help locating a man in the theft and unauthorized use of a credit card, and they provided a surveillance camera photo Thursday showing the suspect at a Bayport convenience store.

The police said the card was stolen from the victim's vehicle, and the suspect used it at a 7-Eleven at 863-865 Montauk Hwy., Bayport, at 1:40 a.m. March 7. He used it to buy two sandwiches and 10 packs of Newport cigarettes, according to police.
