Damiano Cunego, Alessandro Ballan and Lampre team members among 27 facing doping charges

MANTOVA, Italy - Former world champion Alessandro Ballan and 2004 Giro d'Italia winner Damiano Cunego were among 27 people indicted on doping charges on Friday.

The preliminary judge in Mantova set a hearing date for Dec. 10 after prosecutor Antonino Condorelli's report following a lengthy investigation.

The case mainly involves past and present members of the Lampre team, including general manager Giuseppe Saronni, and centres around pharmacist Guido Nigrelli.

Disgraced former Tour de France leader Michael Rasmussen, Mauro Santambrogio and Marzio Bruseghin are also among the 18 cyclists indicted.

In a statement, Lampre says it has "utmost faith in the team members involved" and that "their complete innocence of all charges will be proved."

The story first broke two years ago, following a three-year investigation by Condorelli.
