Three suspects have been arrested in Kenya in connection with the murder of former Bermuda Marathon champion Richard Tirop Kessio.

The three are believed to be ringleaders of a gang that has terrorised residents of the western city Eldoret, Kenyan news site Citizen Digital reported.

Mr Kessio and a friend were killed on the outskirts of the city last month.

Mr Kessio, 43, who was Kenyan, won the Bermuda Marathon three times between 2010 and 2014.
