Lyon fans were furious after their defeat by West Ham as supporters stayed behind in protest after full time, with some starting fires in the stands and fighting with riot police.
Dozens tried to storm the pitch at the Groupama Stadium while West Ham's players were celebrating their win but were stopped by steel fences.
The supporters' anger was aimed at their own team, who are wallowing in 10th in Ligue 1, rather than the Premier League visitors, who beat the French side 3-0 to dump them out of the Europa League at the quarter-final stage.
