The suspect wore sunglasses and passed a demand note to a teller at the Bank of America branch on 1234 Boylston St. on Thursday and then took the letter back, according to authorities.

Brookline police are searching for a woman who robbed a local bank last week.

A police spokesman confirmed Tuesday morning that the suspect remained at large but declined to say whether she made off with any cash. She did not show a weapon.

Anyone with information about the case is urged to call police at 617-730-2222.
