An Assonet man was arrested Monday afternoon in connection with an unarmed robbery at the Martha’s Vineyard Savings Bank on Palmer avenue in Falmouth.

A high-octane mainland manhunt for two suspects who were allegedly involved in a wild crime spree in Braintree last week led police to the tiny town of Aquinnah on Saturday night, where one of the suspects was found holed up in a private home.

William Brymer, 31, of Quincy, was arrested without incident by a large contingent of local police late Saturday, following a tip that eventually led them to a private home on Lobsterville Road in the remote western reaches of the Vineyard.

A $3, 380 bank robbery in Edgartown Tuesday morning led to a high-speed chase and a bizarre showdown in the woods near county airport runways between police with guns drawn and a man firing arrows from a high-powered bow.

The man, later identified as 35-year-old William E. Sweeney of Tisbury, was quickly arrested after tense moments during which police say they almost opened fire.
