A bank in Westbury was the latest target in a series of attempted bank robberies around Nassau County this past week.

Authorities say a masked 5 feet, 8 inches tall male entered the Bank of America on Post Avenue on Wednesday afternoon, slipped the teller a note demanding money and threatened the use of a weapon. When the teller walked away, he ran out the back without any money. No weapon was used, and no one inside the bank was harmed.

A similar robbery attempt occurred at the Chase bank on North Village Avenue in Rockville Centre at 12:30 p.m. the previous day, according to police. In that case, a suspect with a similar physical description also slipped the teller a note demanding money, threatened a weapon and fled when the teller walked away from their station.

The next incident occurred 30 minutes later at a TD Bank on Franklin Avenue in Garden City. The teller was given a note asking for money and threatening the use of a weapon by a man once again described as 5 feet, 8 inches. The teller complied and the suspect left with money.

No one was injured in any of the incidents.

A security presence was noticed Thursday at the Bank of America location - something customers told News 12 they were hoping to see.

Nassau police have stated that they are looking into whether this could be the work of one person. They ask anyone with information to contact Crime Stoppers at 1-800-244-TIPS.
