The FBI is looking for a man who robbed a slew of suburban bank tellers at gunpoint while minding his manners by saying "Thank-you."
Since Jan. 21, the gunman and at least one accomplice robbed six Westchester banks and last targeted a TD Bank in Putnam County on Monday, reported the Journal News.
The man is described to be black and medium height who wears an assortment of hats ranging from a red Yankees cap to one with a black skull and white bandana.
Each time he entered a bank, the robber drew a handgun on the tellers but did not fire and said the phrase 'have a nice day' upon leaving, said New York FBI spokesman James Margolin.
Several county police departments including Briarcliff, White Plains, Bronxville, Westchester, Putnam, as well as the New York State Police Department are all investigating the robbery spree alongside the FBI.
The Crime Stoppers hotline has offered a $2,500 reward for information that will result in an arrest of the man.
There were 241 New York state bank robberies in 2009, which is down from 499 in 2008, reported the Journal News.
The FBI has not returned our call for comment.
