Kenyan world record holder Agnes Tirop has been found stabbed to death at her home in the western town of Iten, with police treating her husband as a suspect.
The two-time World Athletics Championships bronze medallist, who finished fourth in the Olympic 5,000m final two months ago, was 25.
A criminal investigation is now underway into her death, with police saying her husband has gone missing.
On Wednesday, crime scene investigators were at the house of Tirop, who police say was reported missing by her father on Tuesday night.
