Though it was outlawed in March, 2002, the Mungiki movement continues to exist, and continues to engage in violently criminal behavior:
The notorious Mungiki sect is back with all the insecurity this represents.
Its main target as has been the case since the gang reared its ugly head is the matatu business from which it demands money. Matatu crews and owners are expected to pay some kind of protection money daily, failing which the consequences are brutal.
Matatu owners, drivers and conductors have been killed and maimed for refusing to obey. In Nairobi, the public transport has resorted to withdrawal of services to express their disgust, anger and woes.
But it is not just in Nairobi where the Mungiki menace is a security threat. In Kahuro Location in Murang’a District, the sect gangsters reign supreme and it is said to be their main hide-out. The situation is so grave that Central PC Mr Kiplimo Rugut has ordered a 24-hour police surveillance of the location.
