The bald-headed bandit put a note inside the flowers at the Bank of Smithtown in Chelsea.

Call this crook the Romeo robber.

Cops released security-camera images Monday of a thief who knocked off a Manhattan bank last week and gave a teller a bouquet of flowers.

The bald-headed bandit put the bouquet to good use, pulling a note from inside the flowers and handing it to a teller at the Bank of Smithtown on Seventh Ave. in Chelsea last Thursday.

"Give me all your $100's, 50's!" the note read. "Don't be a hero!"

The teller complied,forking over an undisclosed amount of cash, police said.

The robber left the bouquet behind - and took off on foot, police said.

The robber, who struck shortly before 9 a.m., was described as a black man in his early 30s, about 5-foot-9. He wore a Navy blue T-shirt, jeans and white sneakers.
