Matian'gi said that his ministry has received complaints from matatu owners that there are gangs intimidating and extorting money from matatu operators and their clients. 

In a statement, Matiang'i said that these gangs take from matatus as much as Sh50,000 to give them license to operate. 

A few years ago, such gangs were the order of the day in Nairobi's low-income areas like Kibera, Githurai and Mathare.
