Costa Concordia's Captain Schettino returns to ship

The Italian captain of the Costa Concordia ship, Francesco Schettino, has returned to the wreck for the first time as part of his manslaughter trial.

He denies the charges of manslaughter and abandoning ship, which could see him jailed for up to 20 years.

He told reporters that the ship is the custodian of "little secrets" but that the trial will reveal them.
