According to French television channel RMC Sport, Galtier and his son John Valovic-Galtier were taken into police custody at 8:45am on Friday as part of an investigation into alleged discrimination at Nice.

The pair were summoned by Investigators looking into accusations of racism at the Ligue 1 club. 

Galtier and his son can only legally be kept by investigators for 24 hours, before they are either released or placed under arrest and later brought before the court to decide on legal action.

French newspaper L'Equipe claim the pair are facing accusations of racism from ex-Nice sporting director Julien Fournier.

Their report states that Galtier himself is alleged to have made 'discriminatory, racist and Islamaphobic remarks' during his year at the club by Fournier. The latter is also said to have spoken in court last month.

Galtier is understood to have always firmly denied such accusations and has even filed a complaint. 

A number of Nice players and coaches, as well as president Jean-Pierre Rivere and reserve manager Didier Digard, are believed to have already been interviewed by investigators.
