Clerk, AK could not arrest any doctor, because they are not Police. Why the "doctor" (who is not a doctor, but a herborist) could be arrested only now ? Because now in Kenya there is the law against who administers doping, such as in Italy, Spain, France, but not in UK and US.
About Seppelt, I already gave my thought in the past : I respect him for what he did in Russia, his investigation (with the aid of whistleblowers) was deep and clear, but I absolutely don't respect him for what he did in Kenya. I stay in Kenya long time, I know the situation on the ground, I was the first informing about kenyan doping (of second and third level athletes) directly the Chairman Isaia Kiplagat in 2012, and I was the only coach Seppelt spoke with. He CREATED the situation for having a scoop, and now continues with fake documentaries, that don't explain anything but produce a widespread idea that all the best athletes are doped.
His doctors are not doctors, his athletes are not athletes, his contacts don't have anything to do with the real athletics (when he showed, in his third documentary, the interview with one "athlete" saying his teammate died for EPO, this was not an athlete but a farmer, the dead athlete never competed in Kenya in any Marathon and never was in top 50 in any local race, but Seppelt created a "virtual link" with the best Kenyan who never had any contact and any knowledge about this man).
But I can say something more. The IAAF antidoping department, under the guide of Kyle Barber, well knows that 95% of the accusations regarding Kenyan runners are fried air. They know the top athletes are clean, for the simple reason they, together with WADA, carried out MORE TESTS ON THE BEST THAN EVERY OTHER ATHLETE IN THE WORLD, and this in order to guarantee they are clean, for avoiding every further problem.
You can directly read the words of Sebastian Coe, when explains there are no problems with top Kenyan athletes because they are tested more frequently than any other top athlete in the World.
Among my athletes, for example, Jairus Birech was already tested, this year, 13 times for urine and 3 times with blood, Caleb Ndiku 12/3, Thomas Longosiwa 9/3 (and before Trials two tests in two following days, the first from IAAF and the second from WADA). I don't know how many times Asbel Kiprop, Rudisha, Eliud Kipchoge, Vivian Cheruiyot and other big were tested, but I can suppose about the same amount of my athletes.
So, I repeat again, one thing is not to be compliant with WADA rules about the local antidoping ( that is a fact of organization and availability of money, that Kenyan Government didn't set aside till when was forced by the threat
to be banned by Olympics), other thing to have suspicions about the top athletes, thinking they are not controlled : THIS IS A BIG LIE.
I don't know who is this English amateur who improved from 33' to 32' after a period in Lornah Training camp. Everything could happen, but I can't be surprise if an "amateur" with his normal training, going for some week in Iten and training in altitude with more volume, can improve of one minutes going back at sea level. If we have to think of doping every times some athlete can improve, really we are mentally sick, and don't know anything about the "basic effects" of training.
