Now why didn't someone think of this years ago?   Maybe could have foiled more robberies...

A would-be bank robber was foiled after a teller shut the security door and told him the bank was closing.

Cranston police told The Providence Journal that it happened Thursday around 7 p.m., closing time at a Citizens Bank counter inside a grocery store.

Major Robert W. Ryan says the man gave the teller a note written on a ripped paper plate that said, "This is a robbery."

The teller put down the security curtain, told the man the branch was closing and closed the security screen door. Ryan says the man walked quickly away, empty-handed.

Police are looking for the man.
