A West Babylon bank was robbed Monday around 3:45 p.m. after a man gave a note to the teller demanding cash, Suffolk police say.

The robbery took place at the Flagstar Bank on Montauk Highway. Once the teller complied with the note, the robber walked eastbound to a sedan getaway car waiting for him.

It wasn’t immediately clear how much money he was able to leave with or if the man was armed.

Police are looking for a thin, bald, white man in his mid-40s with graying facial hair. The man also had on a dark-colored jacket at the time.

Detectives are asking anyone with information to call the Major Case Unit at 631-852- 6555 or anonymously to Crime Stoppers at 1-800-220-TIPS.
