The head of security at Lens has rejected talk that his team were heavy-handed with Manchester United fans.
United's 1-0 win over Lille in the UEFA Champions League on Tuesday night was overshadowed by events off the pitch.
Trouble broke out at Lens' Stade Felix-Bollaert stadium with several fans appearing to be crushed due to over-crowding in the United end of the ground.
Tear gas was used by police to try and stop the supporters from climbing barriers as they tried to avoid being crushed.
Uefa has launched an investigation into the incidents, but the chief of security at Lens, Damien Vanoise, has defended his colleagues' actions.
"I think we responded to what happened," Vanoise told French radio station RTL.
"We didn't intervene by chance.
"There was not even a problem of communication. From the moment we saw the supporters who were trying to pull on the railings, what is the interpretation we can make from that - us, as security guards? For me, it is violent behaviour."
Vanoise also insisted that no one got crushed and that there were not too many people in the visitors' stand.
"I can tell you that nobody was crushed in the wire fencing," added Vanoise.
"There weren't too many people in that stand. The stand was not full."
