A mason died after falling from the sixteenth floor of a building under construction in Kileleshwa, Nairobi.
David Kariuki was among workers at the site along Othaya Road when he slid and fell off landing on his head, police and witnesses said.
He was fixing blocks when he fell off on Monday evening, his colleagues said.
He was rushed to a nearby hospital where he was pronounced dead on arrival, Nairobi police boss Adamson Bungei said.
It is the latest such incident to happen in the industry in a series that has seen dozens of workers dead.
Lack of safety gear has been blamed for the incidents at the construction sites.
Many of the workers fall off or are hit by falling objects. For instance, a worker was on Sunday killed after a falling stone hit him in Eastleigh, Nairobi.
He was loading stones onto a crane when one fell off and hit him in the head killing him on the spot.
Construction works at the Kileleshwa site were stopped pending the ongoing probe, police said.
This is the latest such incident to happen in the city in a series at construction sites.
Police said most of the victims do not have protection gear as required. The incidents are pending under probe.
Police with the National Construction Authority and the county government are investigating the incidents.
Meanwhile, police are investigating the death of a man whose body was found lying on the roadside on Kamiti Road, Nairobi.
Officers said the scene where the body was found was secondary as there were no signs of struggle there.
The body had strangulation marks on his neck but had no identification documents.
According to police, the man was killed elsewhere and the body was dumped at the site where it was discovered on Monday.
The motive of the incident is yet to be known. The body was moved to the mortuary pending autopsy and further probe.
Police said they are yet to identify the body as part of the probe into the murder.
Cases of discovery of bodies at various spots in the city are on the rise. The incidents are still pending under probe, police say adding up to two cases are reported daily.
