Incarcerated filmmaker Roman Polanski has promised authorities he will not try to evade justice if they accept his latest bail offer and grant him his freedom.

The Rosemary's Baby director filed a new bail offer on Monday, following two unsuccessful attempts to convince officials in Switzerland to release him from custody.

His filing is said to have listed "adequate guarantees" that he will not run away from his ongoing legal battle, according to his lawyer Herve Temime.

Polanski has been imprisoned since September on the request of Los Angeles law officials, who want to extradite the star to the U.S. to face sentencing over a 1977 sexual assault on a 13-year-old girl.

He pleaded guilty to the charges but fled the country in 1978 before he could be handed his punishment.

Despite calls from his victim to drop the case, Polanski has been refused bail on two separate occasions over worries he is a "flight risk".
