Nassau County police have arrested a Baldwin woman who they said stole a credit card while working as a substitute mail carrier and used it to buy $4,800 worth of goods.

On Sept. 12, 2014, a woman police identified as Shereen Maignan, 25, of 3325 Bertha Drive, Baldwin, entered Nordstrom at Roosevelt Field Mall in East Garden City. Surveillance footage captured Maignan paying for $4,800 worth of merchandise with a Chase Bank credit card, police said.

An East Meadow woman had reported that her Chase Bank credit card had never arrived in the mail -- the same card police said Maignan used, according to police.

The U.S. Postal Inspector also conducted an investigation into the complaint, and determined that Maignan had been filling in as a substitute mail carrier on that route at that time in East Meadow.

Maignan was charged with third degree grand larceny and first degree identity theft. She was scheduled to be arraigned Tuesday at First District Court in Hempstead.
