In his late 30s, powerfully built, a shaven headed Algerian gangster who speaks French, he's the shark-like owner of the Libertine night club, where anything goes and any kind of high (including sexual) is available for a price. Yann's hooked in all over Paris and was formerly a fighter in the Algerian war. For a gangster he's got a code of honour which means everything to him. Volatile temper. Has a close, long standing partnership with Brigitte.
