A former French boxing champion was convicted for attacking two police officers in a protest against the "yellow vest" in Paris.
The 37-year-old Christophe Dettinger was filmed on January 5 and struck with footage that was distributed on social media.
He was sentenced to 30 months in prison.
Eighteen months of punishment will be suspended, and he will be able to exercise the 12 months in the so-called "semi-freedom".
The protests started in mid-November due to fuel taxes, but spread to a revolt against President Emmanuel Macron.
- Who are the Gilets Jaunes?
Dettinger's case and the yellow vest's movement have divided France.
In a separate facility, the restaurant of a French star chef was involved in a suspected arson attack on Wednesday – the second time in two weeks.
The prosecution is investigating whether Yannick Delpech's restaurant L & # 39; amphitryon was retaliated for criticizing the "yellow vest".
What did the court decide?
The verdict was announced Wednesday by the Paris Criminal Court.
It states that Dettinger would spend a year in the "semi-liberty" regime.
That means he will spend the night in prison, but will be free during the day.
In addition, he is not allowed to stay in Paris for six months.
Reports from the courtroom indicated that the followers of Dettinger were satisfied with the verdict. He could have been detained for seven years.
During the trial, he said he made a "mistake" after seeing the police collide with demonstrators.
Why is the case so divided?
Dettinger, France's Cruiserweight Champion in 2007-08, was taken into police custody two days after the January 5 protest.
After his arrest, more than 114,000 euros were raised in a fundraiser for the former boxer. Thousands have left comments on support, including some opposition politicians.
The site was then removed after sharp criticism that violence against the police was tolerated.
Dettinger, a father of three, worked as a civil servant prior to the incident in the south of the city.
Before handing over to the police, Dettinger posted a video of himself on YouTube explaining his actions.

In it he described himself as a "common citizen" who had "reacted wrongly" in anger, after he had seen the police with tear gas and lightning balls (rubber bullet) against demonstrators.
Another demonstrator, Gwenaelle Antinori Le Joncour, spoke on Wednesday in the one-day trial as witnessing the defense of Dettinger.
"He saw a 47-kilogram woman and my eldest son was beaten, he could not stand because there was too much violence," she said in court.
The number of Gilets demonstrators (yellow vest) walking on French roads has gradually dropped – but tens of thousands are still weekly to demonstrate all over France.
Their protests were often violent and caused damage – including some of the most famous monuments of Paris.
Hundreds of injuries and a number of deaths have also been linked to the demonstrations.
Nearly 1,800 people have been tried in court so far, mostly with the destruction of public property and attacks on the police, reports the AFP.
Another 1,400 protesters are still awaiting trial, Prime Minister Edouard Philippe said Tuesday.
Eric Drouet, one of the group's leading figures, is being tried on Friday in Paris for illegally organizing a demonstration.
