A judicial investigation has been opened in Marseille, targeting pharmacies suspected of illegally supplying Toulon players with medication.
According to radio station RTL, "antibiotics, analgesics, but also anabolic steroids" are believed to have been given to players from the triple Europeans champions, although the Marseille prosecutor has told AFP that the case is "far from doping."
After a poor start to the Top 14 season, things just got worse for RCT. Following a notice from France's anti-doping agence, l'Agence française de lutte contre le dopage (AFLD), investigators are looking into claims that "pharmacists in Toulon are suspected of illegally supplying players from RC Toulon with products."
"It is non-compliance of the Public Health Code for drug delivery" Marseille prosecutor Brice Robin told AFP.
"Article 40 of the Code of Criminal Procedure requires any organisation or authority such as the AFLD to transmit the information it has to the prosecutor if it obtains knowledge of a crime or of an offense."
According to RTL, the health cards of several players were found during a search.
Toulon president Mourad Boudjellal has rejected all links to doping.
"I have no worries, it's totally false," Boudjellal told Le Monde.
"I will give a press conference this afternoon to explain it."
Toulon's lawyers denied any wrong doing by the club.
"There is no such case," they told La Provence.
"How can one imagine buying performance-enhancing drugs in a pharmacy? It makes no sense."
