A retired French archbishop is being investigated following a complaint that he sexually abused a young adult woman in the 1980s.

Emeritus Archbishop Jean-Pierre Grallet of Strasbourg has admitted to making “an inappropriate gesture” to the woman while serving as a Franciscan priest. The precise nature of the complaint has not been revealed.

“At the end of the 1980s, when I was a Franciscan religious, I acted inappropriately toward a young adult woman, behaviour that I deeply regret,” said Archbishop Grallet in a statement.
