Magistrates have handed the Italian Olympic Committee (CONI) the files of 47 people who are under investigation for drugs.

Germany's 1997 Tour de France champion Jan Ullrich is included among the list of riders and team members whose details have been passed from Florence magistrate Luigi Bocciolini to CONI's anti-doping czar Giacomo Aiello.

Over 100 people were snared in the 2001 Giro d'Italia police dragnet and are under formal judicial investigation by Bocciolini.

The magistrate is expected to pass more files soon after that initial 47 - which includes 36 riders and 11 team directors or masseurs.

While charges in the courts will be a long drawn out affair the sporting disciplinary process by Aiello could be concluded within weeks.

CONI has the power to punish Italian wrongdoers but under international rules Aiello will only be able to pass on Ullrich's case to the German federation.

It is expected that Italy's most famous and most controversial cyclist Marco Pantani will feature in the second wave of cases to be handed to Coni.

Police found a syringe with insulin in the hotel room of the Mercatone Uno rider in the blitz last summer at San Remo during the Giro.

Aiello has let it be known any rider that does not cooperate fully with the inquiry can expect a long ban that would rule him out of this year's Giro.
