The ex-wife of a French former surgeon on trial for allegedly assaulting or raping 299 patients insisted Wednesday that she "suspected nothing" of his crimes following accusations by the physician's brother that she was in the know and failed to act.

Joel Le Scouarnec, 74, is on trial for allegedly assaulting or raping 299 patients, in one of France’s largest child sex abuse cases.

Retired surgeon Joël Le Scouarnec, 74, has been on trial in the western city of Vannes since Monday in one of the country's largest child sex abuse cases.

A former surgeon is set to stand trial in France for the alleged rape or sexual abuse of 299 victims. Most of them were children who were his patients.

The trial of Joël Le Scouarnec, who is charged with the rape and sexual assault of 299 people in France over decades, is set to begin. The alleged victims’ average age was 11.

The son of a retired French surgeon accused of raping and sexually assaulting hundreds of young patients told a court on Tuesday that Joel Le Scouarnec was a good father - but that the crimes he is accused of are unforgivable.
