Civil activist Okoiti Omtatah was seriously injured after unknown assailants attacked him on Thursday night in Nairobi's central business area.
Mr Omtatah lost four incisors in the 9.20pm attack along Kenyatta avenue.
He was also stitched on the forehead and the back of his head, doctors at the Nairobi Outpatient Hospital told Nation.
“He arrived here about 9.40 pm bleeding profusely and in a semi-unconscious state. We had to stitch his head and do IV fluid resuscitation because he had lost a lot of blood,” a doctor at the facility who requested not to be named said.
Mr Omtatah said the assailants had called out his name before asking him whether he intends to drop a case he has filed touching on the procurement of the Biometric Voter Registration kits.
“When I told them that I will not stop the case they immediately attacked me,” he said, adding that nothing was stolen from him despite carrying valuables that included two phones and Sh10, 000 in his pockets.
He was attacked shortly after alighting from a bus on his way back to town from his office located in the Community Hill area.
He said he had stayed late in office to finalize on a case he intended to file in court next Monday against “illegal payment of MPs for 14 days as from January 1, 2008 to January 14, 2008.”
Last week, Mr Omtatah amended his case to directly include IEBC Chairman Isaak Hassan, CEO James Oswago and Finance Minister Njeru Githae as respondents.
“I will not stop the case because Kenyans are losing almost Sh10 billion in this fraud. I want this money to be recovered from his individuals,” Mr Omtatah said.
He said that he wants the government to make public details of the BVR procurement.
“Omtatah is standing for the right of Kenyans and this is why some people are now fighting him,” activist George Nyongesa, who was among the first people to arrive at the hospital, said.
