Former Nandi Hills Member of Parliament Alfred Keter is missing.
Keter was abducted by unknown people around Lavington area on Sunday afternoon.
He has been a fierce critic of President William Ruto and his administration.
His abduction comes at a time when pressure is mounting on authorities to stop abducting Kenyans speaking up against unpopular policies.
A number of social media influencers and Kenyans have been abducted over the last one week only to be released later.
His abduction was captured in a video that has since gone viral.
The video shows a man believed to pulled out of a black Vehicle in broad daylight as other road users look on.
A voice believed to be that of the missing politician is heard screaming for help and alerting those close by as other voices join in.
Following his abduction, a number of politicians have placed the blame squarely on the government, alleging that it is part of intimidation tactics that have become too familiar in recent days.
"Today, the nation has witnessed the abduction of former Nandi Hills MP Alfred Keter in Nairobi, another incident in a series of proliferating gangland-type kidnappings. This alarming trend, including the abduction of numerous young people that we have consistently and unequivocally condemned, heralds a grim future for the rule of law that Kenya prides itself on." KANU chairman Gideon Moi noted.
Governor James Orengo condemned the abduction, noting that the country is sinking to new low.
"Abductions, killings, terror and ruthless repression Kenya is beginning to look more like Haiti than Haiti. RELEASE CHARLES KETER." Orengo slammed.
