The FBI says the man's notes have just one word: "robery" with one "B."
His latest target was a TD Bank in Peabody on Sunday. He's also suspected of hitting banks in Arlington, Reading and Burlington since Oct. 31. In all the robberies, he's worn sunglasses and either a baseball hat or hood. He's described as white, in his late 30s or early 40s, between 5-feet, 11 inches, and 6-feet-2.
The FBI says it's concerned because the man's becoming increasingly aggressive toward the tellers.
The reward is up to $1,000.
