PAGO PAGO, American Samoa >> A fisherman is dead and another is injured after an accident at sea involving an American Samoa-based fishing vessel.

The U.S. Coast Guard says Pago Pago-based MV Carol Linda was about 700 miles north of the U.S. territory’s main island of Tutuila when the accident happened earlier this week.

Lt. Steven Caskey says the initial report received by the Coast Guard is that the main mast that holds up the boom broke in half and fell on crewmembers.

Identities of the man killed and the injured fisherman who suffered broken bones have not been released.

Caskey says the boat and crewmembers are returning to American Samoa and are expected to arrive Saturday.

The Coast Guard and the U.S. Department of Labor’s Occupational Safety and Health Administration are investigating.
