The body of the man whose vehicle plunged into the Indian Ocean on Saturday morning has been retrieved.
The Kenya Ferry Services said John Mutinda's car sped off the ramp at high speed.
The incident brings memories of the recent Likoni Ferry tragedy where Mariam Kighenda and her daughter Amanda Mutheu drowned on September 29.
It took rescuers 13 days to retrieve the wreckage of their car from the seabed.
The KFS statement on Mutinda's death said, “A motorist driving a saloon car whose registration number plate has not yet been established right away after purchasing ticket drove off to the ramps with high speed to the ocean."
The agency further noted that the driver failed to stop the vehicle despite several efforts by ferry officials to flag him down.
KFS rescue boats, Kenyan Navy and the police and other rescue operation agencies responded immediately.
The search operation to retrieve the car is underway.
Mombasa Governor Hassan Joho earlier said the county government dispatched a unit from the inspectorate department to join the multi-agency rescue team.
