Surveillance footage from cameras outside the Stade de France that captured the chaos ahead of the Champions League final has been deleted.
Critics are now accusing French authorities of trying to cover up the incident.
The French Football Association claims that the films were automatically destroyed because they were not requested by judicial authorities.
The revelation blocks the already hot tones around the authorities' actions before the match.
French police have been criticized for creating bottlenecks at the entrances to the arena and for using tear gas and pepper spray.
"Called to hide their tracks"
A state report states that France's reputation was damaged by the incident and the opposition in the country was not late to catch on when the revelation about the surveillance films came.
- It is called hiding its tracks, says Marine Le Pen, leader of the nationalist party National Assembly.
The police asked for the surveillance videos, but not until it became known that they had been deleted, says a source to AFP.
The Stade de France can keep surveillance videos for up to 30 days, but the servers can only store them for a little over a week.
"On the way to state scandal"
The French police tweet that even if you do not have the material from the arena's cameras, you still have your own available.
But Vice President of the Senate Law Commission, David Assouline, says he was "paralyzed" by the news, adding that it showed an "incredible lack of coordination" between police and politicians.
- We are on the way to a state scandal, says Bruno Retailleau, chairman of the Republicans in the Senate.
The government, however, says that there is enough evidence to take the investigation further.
