The bridge at River Gucha collapsed on Friday morning as Machakos Governor Alfred Mutua and Kisii DG Joash Maangi stood on it.
Some reports indicated that it caved in as they took selfies while others said the Governor had bent to check the depth when the incident took place.
They were with several people who accompanied them to a bench-marking tour.
Mutua and Maangi were pulled out and rushed to Ogembo Hospital in Kisii County in an ambulance.
The Governor dismissed the report about selfies.
“I have been baptised by River Gucha and now I must build a house in Gucha,” he said, as reported by Radio Citizen.
When called by the Star, he said he was safe and that he was having lunch at Maangi’s home.
“The bridge caved in after a crowd of those who accompanied us joined us,” he said.
