The complainant is said to be the sister of the man who attacked Happio in Caen during the French Championships. She reportedly went to the 12th arrondissement police station on Thursday to file a complaint. The latter would also be an athlete, specialist in the triple jump, and also a resident of Insep. She would denounce facts that date back to October 2021. In the temple of French sport, Happio would have had “inappropriate gestures” in the corridors of the establishment, which she would have told her brother, who decided to battle with Happio by attacking him during his training in Caen, shortly before his title in the 400m hurdles. Still according to Le Parisien, the aggressor, also an athlete, would have made a statement at the Caen police station on Sunday evening.
