Serial bank robber at large

(WWLP) - Call him the "Baseball Cap Bandit". Police say a rash of bank robberies all lead to one suspect who wears a Red Sox or Yankees cap.

Police say one man has robbed six banks in western Massachusetts and Connecticut in December alone.

He's usually dressed the same -- sporting a Red Sox or Yankees baseball hat, a dark hoodie, glasses, gloves and a mustache.

According to West Springfield Detective Jay Gearing, his M-O is the same too.

"His MO is walking into the bank, passing a note, demanding money, claiming to have a gun and walking out of the bank calmly," he said.

Despite knocking off six banks, Det. Gearing says he continues to elude police.

"The hardest thing is we don't have a lot to go on, he seems to vanish once he exits the bank we haven't had a lot of witnesses," he said.

Here's a rundown of his alleged haunts:

December 3rd -- The Federal Credit Union in Enfield on Cranbrook Boulevard

December 3rd -- Sovereign Bank in Chicopee on Center Street

December 8th -- Webster Bank in West Springfield on Elm Street

December 12 -- TD BankNorth in Chicopee on Meadow Street.

December 18th -- New Alliance Bank in East Longmeadow on Somers Road.

December 29th -- Westfield Savings Bank in Agawam on Main Street.

Police say this robber is particularly brazen for the fact that he acts often and doesn't disguise himself well. And when he hit the Webster bank in early December on Elm Street, he was across the street from the police department.

Det. Gearing is asking for the public's help to put the Baseball Cap Bandit behind bars, if you see him walking around or about to strike he urges people to call police.
