Elvis has left the bank branch?

UPDATE: Boston Police report the arrest of Patrick Cannon, 54, on Yawkey Way last night - after security guards at the garage where he'd stashed a second car spotted him.

Boston Police are looking for a white guy in a white jumpsuit or graduation-style gown who held up the Cambridge Trust branch at 65 Beacon St. at gunpoint late this afternoon and who may have escaped in a Cadillac.

The Caddy - an Escalade - was discovered abandoned a few blocks away at Berkeley and Marlborough; police were concentrating their search in the area around the Christian Science Center.

The bank was also robbed at gunpoint in May.
