PARIS, Jan 11 (Reuters) - Bastia have been barred from playing at home for three games and given a suspended two-point deduction after supporters of the Ligue 1 club were involved in a series of violent incidents, the French League (LFP) said on Friday. The club have already served one match of the ban when they beat basement side Nancy in Gueugnon, eastern France, last month after they were banned from using their own ground pending the ruling.
