The man, whose name was not known by the time of publishing, was driving a vehicle the make of a Subaru Forester when the unfortunate incident took place.
Detectives from the Directorate of Criminal Investigations (DCI) have confirmed the incident, saying that a three-man gang aboard a motorbike were the perpetrators of the crime.
Photos and videos seen by kenyagist.com showed eyewitnesses crowded at the scene and traffic snarl-up in the area.
Area police boss Dorothy Migarusha stated that the victim had more than 10 bullets pumped into his body.
She added that the victim was rushed to Thika Level 5 hospital for treatment.
It is not clear whether the suspects stole anything from the scene of the crime.
The incident took place just hours after a woman was shot and seriously wounded by thugs on a motorcycle in the Greenspan area, Donholm on Monday, June 21.
She was headed home when the suspects shot her in the chest, grabbed a bag that she had and sped off.
The middle-aged woman was left lying in a pool of blood and is currently fighting for her life in hospital.
