Kenyan coach John Anzrah

Rio Olympics 2016: Kenyan coach John Anzrah sent home after posing as athlete

Kenya said sprint coach John Anzrah "presented himself" as 800m medal hope Ferguson Rotich and "even signed the documents" for the doping test.

"We cannot tolerate such behaviour," said Kip Keino, chairman of the National Olympic Committee of Kenya.

Rotich, who finished fourth at last year's World Championships in Beijing, is set to race in the heats on Friday.

The athlete's agent, Marc Corstjens, said Rotich lent Anzrah his pass so the coach could get a free breakfast in the Olympic Village on Wednesday.
