Somali pirates received a $4 million ransom to free an Italian cargo ship that was seized four months ago with a crew of 16, a member of the gang that held it captive said on Monday.

Italian Foreign Minister Franco Frattini said on Sunday the Buccaneer was freed after "exceptional work" on the part of Somali authorities and the Italian intelligence service. The owners of the Buccaneer, Ravenna-based Micoperi Marine Contractors, said on Sunday the ship was not freed as a result of military action or ransom payment. "We have taken $4 million ransom and freed the Italian tugboat. It has already gone," pirate Aden told Reuters. Andrew Mwangura, coordinator of regional maritime group, East African Seafarers' Assistance Program, said the pirates received $5 million. "They were counting the money last evening," he told Reuters by telephone. The Buccaneer was hijacked on April 11 in the Gulf of Aden along with two barges. It is now on its way to the port of Djibouti escorted by naval vessels.
