Christophe Dettinger

Christophe Dettinger, known as the "Gypsy of Massy" (born 3 May 1981), is a French professional boxer. He was the French Cruiserweight champion in 2007 and 2008. His career ended in 2013. In 2019, he was convicted of punching back two mobile gendarmes after clashes in Paris as part of the Yellow Vest Movement. Three days after punching police at Yellow vests protest, Christophe Dettinger surrendered himself. A website set up to raise funds for the boxer showed that it had received pledges of more than €114,000 The fundraiser was closed after less than 20 hours after officials expressed outrage. Anti-corruption campaigner Christophe Grébert defended the fund, saying it was legal to ask for funds to pay court costs. Shutting the fundraiser, he said, was a "bad signal for democracy".

On 13 February 2019, Dettinger was sentenced to 1 year of prison and 18 months' probation for assaulting two police officers during the protest on 5 January.
