There are several spots in all the major roads entering Kiambu town which is just a few kilometres from Nairobi.These spots are known by motorists to be the most notorious as the traffic officers cling like a tropical tick until they "remove something small".
If claims by the Kiambu matatu Sacco are to be believed, officers manning the busy roads collect about Sh300,000 daily, with each vehicle required to pay Sh100 at the road block.
