World 800 meters champion David Rudisha was on Saturday involved in a plane crash at Imbirikani in Kajiado county.
Journalist James Smart shared the information on Twitter but said the athlete was safe.
"World 800 meters champion @rudishadavid involved in an airplane crash. He is safe," Smart said.
Reports later revealed that Rudisha and his team were returning to Nairobi after attending Maasai Olympics which were held in Kimana area of Kajiado South subcounty.
The occasion which was hosted by Kajiado Governor Joseph ole Lenku is aimed at promoting wildlife conservation efforts.
Witnesses said one of the occupants was injured in the crash.
"All the occupants came out unhurt except one who was rushed to the hospital,” a resident who arrived at the scene immediately after the crash said.
The residents believe the plane, registration number 5Y-BGJ, developed mechanical problems before it went down in a rocky terrain.
The incident comes just two days after two people were on Thursday, killed when a light aircraft they were flying in crashed within Tsavo National Park.
The two included the pilot, a former Kenya Wildlife Service warden, and his co-pilot.
The plane, a Cessna sky wagon, came down as they were trying to drive cattle that included cows, camels and goats out of the park when the incident happened.
