The manager of the Kenyan Olympic athletics team has reportedly been recalled from the Rio Games after an investigation alleged he demanded money to give warnings about doping tests.

The investigation by The Sunday Times newspaper and German television channel ARD into Michael Rotich is a potential new blow to Kenya's sporting reputation after doping accusations in recent months.

Mr Rotich was filmed by the two media outlets allegedly demanding £10,000 ($13,000) for agreeing to warn a British coach about imminent doping tests.

ARD journalist Hajo Seppelt tweeted an Athletics Kenya statement saying Mr Rotich had been recalled "so we can investigate further his role in this."

"These are very serious allegations and we cannot have someone of that character managing our team."
