The International Association of Athletics Federations has suspended the Kenyan Olympic track team's manager over allegations that he sought bribes from undercover reporters to protect athletes from doping tests.
The IAAF says Friday that Michael Rotich, who was sent home from the Olympics in Rio de Janeiro last weekend, is suspended for 180 days while the track governing body investigates.
He is the fourth athletics federation official in Kenya to be put under investigation for attempting to cover up doping.
Also Friday, the athlete caught up in a second Kenyan doping scandal at the Olympics says he has "explained everything."
Ferguson Rotich, who ran on the opening day of track and field in Rio, is being investigated after a coach was found with his accreditation and pretended to be the runner at a doping test.
