Financial Brigade head Jean-Michel Aldebert speaks with the media outside their headquarters in Paris January 26, 2008, to comment on former French trader Jerome Kerviel who is in police custody. Kerviel, the 31 year-old trader blamed for a $7 billion fraud at French bank Societe Generale, was being held for questioning, which under French law can last for an initial 24-hour period before any charges are pressed.
