Police and the coast guard are investigating a possible double murder after two tanker crew were found stabbed to death in the Caribbean.

The incident occurred on the 108,000-dwt aframax RBD Gino Ferretti (built 2011) off the Dutch island of St Eustatius, the Daily Herald reported.

The Italian-flagged ship arrived in Oranje Bay Harbour on Thursday.

The ship’s agent reported the incident.
