Two people were in police custody on Monday after an investigation was opened into suspected doping at this year’s Tour de France by the Arkea-Samsic team, French prosecutors announced. In a statement, the Marseille prosecutor Dominique Laurens said that it was carrying out an investigation into a “small part” of Arkea-Samsic, without specifying who had been placed in custody. Laurens added that the two people in custody had “many health products including drugs in their personal belongings, but also and above all a method that can be qualified as doping”.
