France on Saturday expelled a Russian far-right leader of a football supporters group, Alexander Shprygin, and 19 other fans after the troubles with England fans at Euro 2016.
Shprygin and the others were on a plane that left the southern French city of Nice for Moscow on Saturday. French investigators believe the group, officially ordered out for disrupting public order, includes well-prepared hooligans.
Thirty-five people were injured in fighting between Russian and English fans around the England-Russia match in Marseille last Saturday.
Meanwhile, UEFA began disciplinary procedures Saturday against Croatia and Turkey following flare-throwing incidents at Euro 2016 matches.
UEFA said Croatia was accused of crowd disturbances, racist behaviour, setting off fireworks and throwing objects.
Croatian coach Ante Cacic called the country's fans "sports terrorists" after the incidents which caused a four-minute halt to the match.
UEFA has accused Turkey of a pitch invasion, throwing objects and setting off fireworks.
