Madonna's Use Of Swastika Caused Riot
TMZ spoke with several people who were in the crowd Thursday night (and have been to several of Madonna's recent concerts). They say there were 10 or so "fans" in the audience who started the ruckus ... and those people were overheard yelling about Marine Le Pen.
We're told several members of this group we're holding up signs they'd brought to show support for Le Pen.
Madonna has been at odds with Le Pen ever since she started projecting the leader's face -- with a swastika over it -- during this tour.
We're told local police spoke to members of Madonna's crew the day after the concert ... and said they believe the riot was preplanned by a group of locals looking to cause trouble.
According to our sources, the majority of Madonna fans knew to expect a short show -- as all her club dates tend to be -- so that could not have been the cause of the riot. more on this story
