Mr Muriuki was attacked at Hotel Boulevard on April 30 this year when he was addressing a press conference on the state of the Nairobi County.
The other suspects include EALA MP Simon Mbugua.
Three more suspects have been charged over the attack on city businessman Timothy Muriuki at a Nairobi hotel, where he was allegedly robbed of Sh100,000.
The three, Mr Dishon Peter Mulinge, Mr Ronald Onyango Otieno and Mr Michael Mbanya Wathigo, were represented by lawyer Danstan Omari, who applied for bond. This brings to seven the number of suspects arraigned over the attack, which caused a hue and cry nationwide.
State prosecutor Solomon Naulikha did not oppose the bail plea, saying: “This case will be consolidated with two others where the suspects were released on a cash bail of Sh200,000.”
He urged Chief Magistrate Francis Andayi to pronounce similar terms as in the two previous files. Mr Naulikha said the three files would be consolidated into one and the suspects charged jointly over the attack.
The three denied the offence, which carries a mandatory death sentence upon conviction or life imprisonment.
