Orsi, who resigned from the state-owned aerospace and defence group a few days after his arrest, denies any wrongdoing. He was released from jail because the terms that allowed prosecutors to keep him in custody ahead of a trial had expired. Orsi's trial will begin on June 19 after a judge ruled on Friday that there was enough evidence for a procedure to start immediately, legal sources close to the case told Reuters.
In an e-mailed statement, Orsi's lawyer Ennio Amodio said on Saturday that his client had sought to bring order and transparency to a company hit by internal power struggles, and that he was confident truth would prevail at the trial.
