The National Police Service has offered a Sh2.5 million cash reward for information that will lead to the arrest of five men who assaulted former lobby group chairman Timothy Muriuki.
The police said the attackers, who were captured on camera physically attacking the ex-Nairobi Central Business District Association (NCBDA) chairman, have since gone into hiding.
"The suspects are wanted by police to answer to charges of robbery with violence," a statement by police said.
The gang disrupted and attacked Mr Muriuki when he was holding a news conference at Hotel Boulevard regarding the deplorable state of the county.
The gang alleged that Mr Muriuki organised the event to mudsling Governor Mike Sonko's administration.
On May 2, Central Police division boss Robinson Thuku said the incident was reported at the station and detectives were working to apprehend the assailants.
Part of Mr Muriuki's statement says: "Let us separate politicking from service delivery and let us give Governor Sonko a chance to deploy his delivery team, part of which was sworn-in hardly a fortnight ago."
It adds that "Even as we demand that the governor play his part in making Nairobi better, let us bear in mind that Nairobi — which was the ultimate theatre of the dreadful political pandemonium of 2017 politics — was literally ungovernable until the beginning of 2018."
