An inquiry has been opened into suspicious betting patterns concerning a match between Lens and Istres in France's second division last week, a judicial source told AFP on Tuesday. Lens won the match on Friday 1-0, thereby securing their status in Ligue 2. However, Istres coach Jose Pasqualetti revealed after the match that bets were suspended prior to the game due to an abnormal amount of bets being placed on a Lens victory.
