The former Olympic swimmer Amaury Leveaux is in police custody in Paris, facing allegations of violence against his partner and their six-month-old child. According to reports from BFMTV, Leveaux was detained at a police station in the 8th arrondissement, where he lives. He is suspected of threatening his partner and assaulting their infant, who required hospitalization. Medical professionals are concerned about the possibility of shaken baby syndrome, a condition caused by violent shaking that can lead to serious brain injury. Leveaux, who retired from competitive swimming in 2021, is a decorated athlete with four Olympic medals to his name. He earned a gold medal in the 4x100m relay at the 2012 London Olympics, swimming alongside Fabien Gilot, Clément Lefert, and Yannick Agnel. Agnel, who was part of that relay team, was later convicted of rape by a departmental criminal court. This is not the first time Leveaux has faced legal troubles. In 2016, he was arrested after a violent argument with his wife, who claimed he threw her head against a wall and slapped her. However, he was acquitted in March 2017, as the court determined that the incident involved mutual violence during the dispute. In addition to the current custody, Leveaux has also been involved in a separate legal case related to cryptocurrency fraud. A complaint was filed at the end of September 2025, and he was recently brought before the Paris judicial court, which will determine the next steps in the case.
