Commissioner General Chihuri said this at a police passout parade held at Morris Depot in Harare this Thursday.
He said law enforcement agents are aware of plots by a certain political party outside the inclusive government to destabilise the country.
Commissioner General Chihuri added that the concerned political party is allegedly distributing flyers inciting people to engage in a mass action next month and not to participate in elections.
He added that police will not helplessly watch the countryâ€™s peace being disturbed but will deal with the culprits according to the laws of the country.
â€œRight now we are aware that there is a small political party outside the government which wants to start mass protests in early March 2012.
â€œThey have planned to start from Africa unity square employing dirty and desperate tactics such as hunger strikes and mass protests.
â€œThe agenda is to try and overthrow the government,â€ Commissioner General Chihuri said.
Commissioner General Chihuri also took the opportunity to remind Zimbabweans that the organisationâ€™s mandate of maintaining peace and security can only be achieved by increased police visibility.
This follows complains by some people to the effect that there are too many police officers manning the countryâ€™s roads.
â€œLet me state categorically that the reckless and misguided call to remove the traffic police from the roads is a non-starter.
â€œBy nature of their job, police operate from out there and not in offices.
â€œThe police must be vigilant and must continue to be out there to ensure total peace,â€ Commissioner Chihuri said.
A total of 290 officers graduated after completing a six months coarse.
The graduation ceremony was attended by the Commander of the Zimbabwe Defence Forces, General Constantine Chiwenga, Commissioner of Prisons, Major General Paradzai Zimondi, Malawian Police Service Senior Deputy Commissioner, George Kainja, senior government officials among others.
