CHELSEA, MASS. (WHDH) - CHELSEA, MASS. (WHDH) – Police are searching for a pair of individuals suspected of attacking a man in broad daylight and beating him with a baseball bat at a park in Chelsea on Monday morning, officials said.

The victim, described as a man his 20s, suffered a blunt trauma injury to his head, Chelsea Police Chief Brian Kyes said in a tweet.

The victim, an off duty security guard for Alliance Security, was taken to Massachusetts General Hospital where he remains in critical condition.

The suspects reportedly tossed the bat in Island End River before fleeing down Commandants Way toward Spruce Street. It was later recovered by a state police dive team.
