New Canaan police are looking for a woman who attempted to make fraudulent credit card purchases at CVS Pharmacy, 94 Park St.

A store manager called police April 16 to report that the woman attempted to make two separate purchases at 2 p.m. April 15, the report stated. One of the transactions went through for a total of $484, which included a $400 gift card, diapers, baby formula and Easter cards, police said.

The woman then asked for a second transaction, which included another $400 gift card and other items, to be rung up separately, but after several attempts, the purchase was not successful, according to the report. At that point, the manager told police, the woman became agitated and loud.

The manager asked to see the card and she noticed that there was no security code on the back of it, police said. She called the credit card company and learned that the card had been flagged for possible fraudulent activity, according to the report.

Since the woman still was agitated and there were other customers in the store, the manager returned the card and canceled the transaction, police said.

The woman is described as black and wearing a black hat, workout-style pants and shirt and sneakers, police said. Witnesses saw her get into a white Mitsubishi sedan, driven by a black man, in the CVS parking lot, according to the report.

Police said they're looking into a surveillance tape to try to identify the woman.
