The authorities in France seek for an avid cyclist fan who struck the Tour de France on Saturday, an incident punishable by up to a year behind the prison, as the organizers of the event planned to sue the naive, brandishing audience, reports.

The prosecutors started an investigation in Brittany on Sunday to discover the smirking sign-holding lady who, according to the Daily Mail, caused a pile of blood during the famed French race.

The woman, who initiated the wounding accident on the first stage of the Tour de France, is able to shut up for a year—photos that hit the sign 'Go! Gran, Grandad,' in French and German.

The spectator has left the site before investigators arrived, says a Finistere gendarmerie spokesperson.

"Before the investigators arrived, the spectator who caused this tragedy left the site," added the official. "To try to find her, everything is done.

"She had blue pants, a red and white striped sweater, and a yellow waxed jacket."

The prosecutors reportedly started a criminal inquiry on the grounds that they "caused a willful violation of safety rules and damage to someone who could have worked until three months."

According to the mail, the offense in France can be punished for up to a year in prison and an amount of around £13,000.

Meanwhile, the Tour de France organizers aim to sue the oblivious cyclist fan, according to AFP.

"We sue this bad-behaved woman," stated AFP director of tour deputations, Pierre-Yves Thouault.

"We do that so we don't spoil the show for all the small few folks who do so."

During the race, Tony Martin collapsed and sent him into the panel, causing other riders to crash. The derailment of the race caused damage to the riders and severe injuries.
