A new audio recording has emerged of the first contact between an anonymous Italian port officials and the Costa Concordia liner after it hit a rock off the Tuscan Coast of Giglio Island.

The crew member assures he was checking out the reasons for the black-out, but he does not mention that the ship had hit a rock.

The recording was broadcasted by Sky Italia. It was made at around 10pm on Friday.

Captain Francesco Schettino is under house arrest, facing charges of manslaughter and abandoning the ship. He is facing a least 12 years in jail if convicted

Eleven people have been confirmed dead and 21 others are still missing. Three more bodies were found on Thursday, a French couple and a Spanish man of Majorca.
