The man was found on the driver's seat and seemed to have died elsewhere before he was placed at the scene.
Police at the scene told News24 that they would not rule out foul play in the incident.
" There is likelyhood foul play was involved. We will see," a Policeman who asked not to be named told News24.
According to The Star, the body was moved to the Nairobi City mortuary and it is yet to be identified.
Police handling the matter say they will conduct a post-mortem exercise on the body to establish the cause of death.
No arrests have been made so far.
