Accused of sexual assault by several women, he was under judicial and canonical investigation from November 2022 to December 2023 when the case was closed without further action.

He is pastor of St. Anne of the Butte-aux-Cailles [fr] in the 13th arrondissement of Paris and chaplain of the French National Coordination of Young Christian Professionals.
