National Security Minister, Dr Chris Murungaru, yesterday said the Mungiki sect does not exist.
Murungaru said the Government has wiped out the sect and those responsible for the Kayole terror were "common criminals."
"We have dealt with Mungiki. They are over and dealt with. The terrorists in Kayole are organised criminals using the name of Mungiki to spread fear and terror among Kenyans," said Murungaru.
He was speaking after opening the Public Service Integrity Implementation Programme. He was flanked by Internal Security Permanent Secretary, Mr Dave Mwangi.
Murungaru termed those responsible for the Kayole terror as extortionists who are resisting Government move to instil sanity in the matatu industry.
"This is organised crime. They are normal criminals who are preying on the matatu industry. They are an extortion ring which we will destroy," said Murungaru.
Meanwhile, public officers who fail to perform will be sacked, Murungaru warned yesterday.
He said every officer shall be held accountable for what they individually do or fail to do.
"There would be no passing of the buck," he said.
He said all institutions must provide adequate, quality and cost effective service and avoid self serving tendencies.
He said the retention of any institution or individual will be pegged on their continued relevance and productivity.
The minister said the Government will place great responsibility on public service accounting officers. He said public service had been characterised by wastefulness, negligence, inefficiency, insensitivity, corruption and bad governance.
In its present state, the public service may not effectively deliver the Government pledges and meet people's aspirations, he said.
He told PSs and PCs to focus on the fight and prevention of corruption and restoration of integrity in pubic service.
"No meaningful gains in any sector can be achieved unless we eliminate corruption and then prevent it from recurring," he said.
He said public service values must guide the behaviour of public officers and assured the officers of the Government commitment to fighting corruption and achievement of zero tolerance to the vice.
