BOSTON (AP) - Boston police are investigating what appears to be a suicide on Red Sox owner John Henry's yacht.

Police spokeswoman Cheryl Fiandaca says that the victim is a man 28 to 30 years old.

She says that when firefighters and police arrived at the yacht Monday, they found the man in cardiac arrest. She says attempts to revive him were unsuccessful.

It wasn't clear who called authorities. Police did not release the man's identity.

Fiandaca says the man may have been working on the yacht. It was docked at Rowes Wharf near the city's financial district.

Boston police were referring additional questions to the Red Sox. The team hadn't yet issued a public statement.
