Kenyan sevens duo charged with gang rape
Wanyama, 23, who captained Kenya's sevens academy team to win the Victoria Sevens tournament in Zimbabwe in March, and Olaba, 22, are both suspended from the national squad currently in Singapore for the eighth leg of the World Sevens series on April 28-29.
Both players denied the charges when they appeared before Nairobi chief magistrate Francis Andayi. If found guilty they could face up to 15 years in prison.
Wanyama and Olaba were released on bail and ordered to appear in court for the next hearing on May 16.
Wanyama was suspended by his club, Kenya Harlequins pending investigations by Kenyan police.
Earlier in the month the Kenyan Rugby Union released a statement on the matter.
"The Kenya Rugby Union ( KRU) has been made aware of reports about alleged sexual misconduct involving a contracted Kenya Sevens player.
"The matter will be reviewed as soon as practicable by the KRU, in line with existing procedures for all contracted players.
"It is also important to note that with a report having been made to law enforcement authorities, the KRU cannot comment further about the allegations pending the outcome of investigations.
"KRU wishes to state that it does not condone sexual harassment or any other activity that goes against the spirit of World Rugby Regulation 20 and remains committed to continued respect, empowerment and increased participation of women in all aspects of the sport of rugby,"
