Russian football activist Alexander Shprygin was expelled by France for the second time in four days on Tuesday, as police again fired water cannon and tear gas at Euro 2016 fans.
Shprygin, who has been linked to Russian far-right causes, was first expelled on Saturday and his visa cancelled over fan violence between Russian and England supporters.
He was arrested on Monday at a Toulouse stadium where Russia were playing. Shprygin was put on a plane to Moscow late on Tuesday, an Interior Ministry spokesman told AFP.
French prosecutors have largely blamed violence in Marseille on June 11 on the Russian supporters, and Shprygin was among fans rounded up following that incident.
Investigators believe he returned to France after flying to Barcelona and crossing the border by car to reach Toulouse where Russia lost 3-0 to Wales on Monday night.
Shprygin put pictures of himself at the Toulouse stadium on Twitter and was detained as the game began.
The Russian activist, who has been pictured with President Vladimir Putin, told AFP before he was detained again that he crossed the Alps to get into France.
Shprygin again posted pictures of himself on an Aeroflot plane taking him back to Moscow.
French authorities expelled a total of 20 Russian fans on Saturday with Shprygin claiming that four of them had managed to get back into France for their country's last match.
Russian diplomats complained to France over the treatment of their fans before the 20 were ordered out.
Russian fans are at the centre of a French inquiry into disturbances around England's June 11 game against Russia in which 35 were injured, mostly England fans.
England supporters Andrew Bache, 51, and Stewart Gray, 47, remain in comas fighting for their lives, French officials said.
