The FBI and police are looking for a robber who wears a red baseball cap and has hit at least three banks in New Jersey since August.
The FBI says the man threatened the teller in all three robberies before making off with cash.
He wore sunglasses during one robbery, gloves during another and the red hat in all three.
He struck most recently on Saturday at the PNC Bank on Martine Avenue in Fanwood.
Authorities ask anyone with information to call the FBI at 973-792-3000.
