In the TVM investigation, the police did not limit the extra doping test for samples withdrawn 29 July of the six remaining TVM-riders in the race (Jeroen Blijlevens, Bart Voskamp, Servais Knaven, Steven De Jongh, Serguei Outschakov and Sergei Ivanov). On 20 August 1998 they also called in these seven riders for interrogation and submission of samples for additional doping control: Michel Lafis, Tristan Hoffman, Hendrik Van Dijck, Peter Van Petegem, Laurent Roux, Johan Capiot and Lars Michaelsen. As one of these riders, it was either Capiot or Michaelsen, refused to submit samples, the total number of tested TVM riders was 12. In May 2001, during the final court hearing in the TVM trial, the medical expert witnesses stated, that from this tested group the test results had proofed, that the following six were "very likely" to have injected the specified doping substances:[30][31][32]
Jeroen Blijlevens (EPO and corticosteroids).
Bart Voskamp (EPO and corticosteroids).
Serguei Outschakov (EPO and corticosteroids).
Servais Knaven (EPO).
Laurent Roux (amphetamines, corticosteroids and cannabis).
Tristan Hoffman (amphetamines)
All of the six riders testing positive, refused in court ever to have used doping. The court however found sufficient amount of evidence had been presented (104 EPO vials seized from a TVM-car in March 1998, syringes with EPO remainings found in dustbins located in TVM rented hotel rooms during the Tour de France, as well as other doping products seized from TVM's Tour bus), to conclude that organized doping at the TVM team was conducted in the preparation and during the 1998 Tour de France. Consequently the court handed out suspended sentences from 6–18 months to the team's manager, sports director and soigneur.[33] For unknown reasons, none of the six positive riders had their cases evaluated by a sports court, and thus none of them ever received suspensions for their positive tests.
