Vienna - A blood centrifuge that was allegedly used to dope Austrian cyclist Bernhard Kohl has been possibly found in Budapest, Austrian police said Monday.

Investigations were ongoing to confirm whether the machine found Saturday by Hungarian police in a private home was the one operated by Kohl's former manager Stefan Matschiner, according to a police spokesperson in Vienna.

Vienna  - Stefan Matschiner, the former manager of disgraced Austrian cyclist Bernhard Kohl, was arrested Monday night following allegations by an Austrian triathlete that she had received illicit substances from him, the Kurier newspaper reported Tuesday.

Matschiner's arrest came after Lisa Huetthaler, the 2007 military triathlon world champion, told Kurier last week that he had supplied her with the blood booster EPO and the hormone testosterone.

Berlin  - Austrian cyclist Bernhard Kohl has denied claiming that half the field in cycling is using CERA, the third generation of the blood booster EPO.

Kohl, who has been banned for two years for doping, said via his lawyers that he had never accused other riders of using the drug.

According to a Wiener Zeitung report, Kohl said in his hearing with the Austrian anti-doping agency that the drug was discussed in detail by riders and some thought that "probably half the riders were underway with CERA."
