Grosseto, May 14 - Prosecutors in Grosseto on Tuesday refused a plea bargain from Captain Francesco Schettino's defence team in a preliminary hearing of the criminal trial into Italy's worst maritime disaster since the Second World War. Plea bargain requests from the other five defendants including Schettino's deputy Ciro Ambrosio were accepted. Schettino's lawyers offered a deal of three years and four months imprisonment which was rejected by the prosecution. A preliminary hearing judge will have to rule whether the captain of the Costa Concordia cruise ship and other crew members will face trial for the 2012 disaster off the Tuscan island of Giglio that killed 32 people. Prosecutors have demanded that Schettino be tried for manslaughter, causing the shipwreck and abandoning ship before all 4,200 passengers and crew had been evacuated.
