Five Nairobi businessmen suspected of funding the proscribed Mungiki sect have been arrested.
Police also announced they had obtained information that would enable them to arrest key Mungiki leaders who went into hiding after two days of violence in which armed sect members killed two policemen and injured several other people.
Nairobi police boss Stephen Kimenchu told the Press 148 people believed to be members of the proscribed sect had been arrested and would appear in court soon.
He further disclosed that police had so far gunned down six Mungiki members adding: "We expect to get more by the end of the week."
He said that the second policeman killed yesterday had been on sick leave contrary to earlier reports. He had been attached to Buruburu police station.
"What I do not know is if the attack was related to personal disagreement with the attackers. However, I can assure you that the officer was not killed while on duty that time," Mr Kimenchu said.
