But this case seems to have struck a chord and top names are increasingly speaking out.
The incident comes after a string of high-profile probes into police violence against black and Arab citizens and as concern grows over new legislation that would restrict the right of the media to publish images of the faces of police.
Another French football star, Benjamin Mendy, also took to social media, posting a photo with the words "who protects us from the police?"
Until recently, few French sports stars have been so outspoken, with the exception of the likes of 1998 world champion soccer players Lilian Thuram, Marcel Desailly and Vikash Dhorasoo.
