French authorities have arrested fan leader Alexander Shprygin at the Toulouse stadium only days after he was expelled from the country. The Russian fans' representative said he had "crossed the Alps" to get into France, reports Deutsche Welle.
Shprygin was detained during the game between Russia and Wales on Monday evening, which Russia lost 3-0.
The fan leader's case would be "examined" and dealt with "either administratively or with a judicial procedure," Interior Ministry spokesman Pierre-Henry Brandet said.
Shprygin's arrest comes only two days after he was expelled from France, alongside 19 other fans who authorities suspect played a role in the violence between Russian and English supporters in Marseille. Several other fans were arrested. He has denied any wrongdoing.
On Monday, Shprygin tweeted images from what appeared to be the Barcelona airport. He added that he had to travel "in a bit of an unusual way, under the cover of darkness." The fans' representative most likely entered French territory by land.
