Kenyan coach expelled from Rio after allegedly posing as 800m runner Ferguson Rotich

A Kenyan track and field coach has been kicked out of Rio after allegedly posing as an athlete and giving a doping sample.

A source says that Kenya's sprint coach John Anzrah presented himself  as 800m runner Ferguson Rotich. He even signed the doping papers and gave a urine sample under the name of Ferguson Rotich.

"We cannot tolerate such behaviour," said Kenya's Olympic Committee's official Kip Keino.

Keino also said that  John Anzrah was not part of the the Kenya's Rio Olympic staff and has arrived to the games by himself.  

Anzrah had presented himself  to doping-agents by using Ferguson Rotich's  Olympic accreditation card. 

Only after the the doping samples where collected the anti-doping agent realized they had the wrong guy.

"When the anti-doping officials met him, they assumed he was the athlete and that he was lined up for testing," the source said.

Kenyan offiials say  sprints coach John Anzrah was staying outside the village in a hotel and but  borrowed Kenyan 800 runner‘s accreditation card to access the Olympic village. After he entered the Olympic village he was stopped for a random out-of-competition drug test meant for Rotich.
