Greg Kelly, a close aide to Nissan Motor Co.'s ousted chairman Carlos Ghosn, denied the allegations against him in a statement issued by his lawyer following his release on bail Tuesday night from a Tokyo prison, where he had been held for over a month.

"I expect that the trial will start soon. ... I believe my innocence will be revealed in the trial," he said in the statement in response to the indictment accusing him of conspiring to understate Ghosn's remuneration for years in securities reports.

Looking tired after his 37 days of confinement, the former Nissan representative director left the Tokyo Detention House around 10:45 p.m. on Tuesday.
