PARIS — Riders from a second-tier French cycling team were questioned Tuesday in connection with a probe into suspected doping, according to two officials with direct knowledge of the investigation.

One official, who spoke to The Associated Press on condition of anonymity because he was not authorized to publicly disclose details of the preliminary investigation of BigMat-Auber93, said authorities are investigating the possible sale, purchase and possession of doping products, including EPO.

A second official said the riders were questioned at the public prosecutors office Tuesday in Creteil, on the outskirts of Paris. The official, who also spoke to The AP on condition of anonymity because the case was still under investigation, said a doctor had also been taken in for questioning by police Tuesday.

The BigMat team consists of professional and amateur cyclists. It was not immediately known how many of the cyclists questioned were professionals.

One professional cyclist who no longer rides for BigMat said he was also questioned.

Frenchman Arnold Jeannesson, who placed 15th at this year's Tour de France with the FDJ team, told the website of sports daily L'Equipe that he had been questioned on Tuesday.

"I was questioned because I was a rider on the team in 2008. I couldn't bring anything to the inquiry," Jeannesson told L'Equipe's website. "It makes me angry because I'm going to be associated with this. It's going to be spoken about more than my 15th place at the Tour de France."
