The officer hanging at the rear of the Toyota Landcruiser pickup belonging to one of the police stations in Narok county lost grip and landed into a water puddle.
The driver was speeding on a rough road full of water pools after a rainfall.
The vehicle hit a ditch and tossed the cop up and when he was going down, he missed the grip and landed in the pool of water.
A cameraperson captured the moment as women nearby screamed in shock.
The officer stood and walked towards the direction the vehicle carrying his fellow officers disappeared to.
He appeared to limp but he did not sustain serious injuries.
