Kenyan police have launched a manhunt, after the body of a female athlete was found with stab wounds in the town of Iten, famous for its centre for long-distance runners.
Police say they are looking for the Ethiopian boyfriend of 28 year old Damaris Muthee Mutua, who was born in Kenya but competed for Bahrain.
She is the second female athlete to be killed in Iten in a year.
Last year, Kenyans were shocked by the killing of Olympic runner Agnes Tirop.
