Lille: French police on Tuesday detained 43 Russian football fans and believe some of them could be tried over Euro 2016 violence in Marseille, officials said.
The arrests followed a showdown between the Russians, who were in a bus in southern France heading for their country's next match in Lille, and French authorities.
Police surrounded the bus and forced the Russians to undergo identity checks.
No Russian nationals were arrested on Saturday when Russian and English supporters fought pitched battles in the Vieux Port area of Marseille.
But regional government official Adolphe Colrat said Marseille prosecutors believe they have enough proof to charge some of the supporters over the fighting, which was the worst violence at an international football tournament since the 1998 World Cup.
"We have sufficiently accurate information that at least some of them took part in the unacceptable violence," Colrat said.
The supporters could be charged, released or expelled from France, Colrat added.
Meanwhile, a small group of Russian and English fans briefly scuffled in the northern city of Lille where thousands of supporters arrived in the area for the Euro 2016 football tournament. The situation was quickly dealt with when French police used pepper spray to break up the minor confrontation.
This came after another small group of Russians attacked England and Wales supporters earlier in the day.
Lille is seen as the next potential Euro 2016 trouble spot as Russia play Slovakia there on Wednesday, and England fans also congregate in the northern French city ahead of their match against Wales in nearby Lens on Thursday.
Authorities in the French cities of Lille and Lens, where thousands of English and Russian soccer fans are due to arrive for the Euro 2016 soccer tournament, have ordered alcohol bans running from Tuesday to Friday, officials said.
Both teams have been threatened with expulsion from the competition if the violence seen in Marseille last week is repeated.
Uefa fined the Russian Football Federation and gave it a "suspended disqualification" for attacks inside the stadium on Saturday.
A small group of Russians appeared to provoke English fans who were in a bar near the northern city's central train station, Reuters photographers said.
The English responded throwing chairs, but the situation was calming down when police arrived.
