Drug cheats will continue to target-test athletes at the Athens Olympics following further information given to the International Olympic Committee.
Two track and field gold medallists have already been thrown out of the Games as a result of the enhanced testing programme and though that statistic is a record in itself, IOC medical commission chairman Arne Ljungqvist is predicting there will be more to come.
Rumours were rife around the Olympic Stadium last night that a high-profile athlete had tested positive, although this so far remains unconfirmed.
Ljungqvist preferred to highlight the findings that have been unearthed, including Hungarian discus thrower Robert Fazekas, whose expulsion from the Games came just 45 minutes before he was due to receive his gold medal. Fazekas almost failed to provide an adequate sample amid suspicions that he was attempting to deposit someone else's urine into the test tube.
"We already had some information on the Hungarian discus thrower, so what happened was no surprise," said Ljungqvist, who is leading the fight against drugs as both a member of IOC and as senior vice-president of athletics' governing body, the IAAF.
"What he did was almost stupid. But it does highlight the efficiency of the testers and, more importantly, shows that in 2004, at the highest level of competition, with the most sophisticated athletes, coaches and advisors, we are still finding people using the same banned substances as they did 20 years ago.
"That tells us there are no magic, non-detectable substances around otherwise they would have been taken.
"I couldn't say we can find anything because you never know what substances are being tested at any one time but while cheats may be able to get away with it for a little time, eventually they will get caught."
Confirmation that Fazekas was already under suspicion is a clear signal that once the IOC get their teeth into a victim, they are unlikely to let go until they get a firm result.
Information is being compiled from all quarters and is now being actively pursued and acted upon.
"Of course we actively target test," said Ljungqvist. "Why shouldn't we. We can identify risk groups through experience, we get information through active research and we are also assisted by others.
"We are not saying any athlete who performs well is going to be suspected, that would be disastrous. But it would be irresponsible not to act on the information we receive.
"It is the only fair way to do it. We are here to protect the sport, to protect all the innocent athletes who do not take drugs and to protect them from being forced to participate against the cheats."
Ljungqvist also claimed systematic drugs programmes have now changed from the state-run systems of 25 years ago to the more commercially-based ones in operation now.
He fears the BALCO scandal may be repeated, which he understands discredits sport in the eyes of some members of the public.
The IOC have already had to suffer the indignity of seeing the evocative return to the ancient Olympia stadium tarnished by the disqualification of women's shot-putt winner, Russian Irina Korzhanenko.
However, rather that, Ljungqvist claims, than allow the matter to be swept under the carpet as it has been in the past.
"The BALCO situation is one that could prevail in any democratic country where action against drugs has not been taken and is a feature of the previous inefficiency in the US system," said the 73-year-old former Olympic high-jumper.
