Two Queens men used fake credit cards about an hour apart on Thursday to purchase merchandise from the Neiman Marcus store at the Roosevelt Field mall, Nassau County police said.

Each faces a forgery charge, and one also faces a charge of criminal mischief for damaging a door as he tried to flee store security personnel, police said.

Early indications are the incidents are unrelated; a police spokesman Friday said detectives have been unable to make a connection between the two.

Kristoff McKenzie, 21, of 147th Street in Jamaica, used a fake card to buy $455 worth of merchandise at about 4:49 p.m., police said.

Store security held him for police, and McKenzie is charged with two counts of possession of a forged instrument.

Police said he had a second fake card on him when he was arrested.

At about 6 p.m., Steven Jackson, 23, of 197th Street in St. Albans, used a fraudulent card to buy $595 worth of merchandise, police said.

When security personnel first tried to hold him for police, Jackson ran into the mall area, police said. After a brief foot pursuit, security was able to apprehend Jackson, according to a news release. But during the chase he damaged a sliding door at the mall.

When arrested, Jackson had three additional fraudulent credit cards, police said. He is charged with four counts of possession of a forged instrument and criminal mischief.

Each man is scheduled to be arraigned Friday at First District Court in Hempstead.
