Two groups clashed over the autopsy report on the body of Kariobangi North Member of County Assembly Joel Munuve, destroying property in the ward.
One group planned a protest in Kariobangi Mwisho Plaza area, Nairobi to dispute the outcome of the postmortem.
Another group opposed the protest which prompted running battles and stone throwing on Tuesday April 29.
Police said the fighting broke between the residents of Kariobangi and Korogocho. The groups were joined by youths from the Boma of the Dandora area.
Police officers responded when the standoff turned violent and dispersed the two groups.
As they were being dispersed, they started pelting stones and robbing people.
They damaged the Mama Margaret Kenyatta hospital guardroom as they engaged police in running battles.
A female police officer was hit by a flying sharp object, which inflicted a deep cut on her forehead, police said.
She was rushed to Mama Margate Kenyatta Hospital, treated, and discharged in a stable condition.
Four other people were injured in the chaos from fragments of anti-riot rubber bullets and have been referred to Mama Lucy Hospital for further management, respectively.
The windowpanes of Mama Margaret Kenyatta Hospital were maliciously damaged by stones that were pelted by the rioters, police said.
Munuve died due to blood clot in the lungs.
A postmortem exercise conducted on the body at the Lee Funeral Home confirmed the cause.
Chief Government Pathologist Dr Johansen Oduor who led the process confirmed Munuve died due to a blood clot in his lungs.
The clot, which began in a vein in his left leg, travelled to the lungs and blocked a key artery, he said.
The postmortem showed that he lacked enough oxygen in his body at the time of his death.
Oduor explained Munuve died from a pulmonary embolism, a condition caused by a blood clot blocking a major artery in the lungs.
Oduor said the examination revealed that Munuve had insufficient oxygen in his body at the time of death.
“When we looked at the body of the late MCA, from external examination we saw that he had cyanosis (darkening of lips and fingernails). This is seen in people who are not getting enough oxygen in the body,” he said.
“There is a blood vessel called the pulmonary artery where blood passes from the heart to the lungs to get oxygen. We saw a big blood clot there which was tightly adherent to the blood vessel. This is what is called pulmonary embolism which can cause sudden death.”
Dr Oduor said further examination was done to trace the origin of the blood clot.
“We tried to find where the blood clot was coming from and upon looking at the whole body, a blood vessel in the lower limb also on the left in the vein called popliteal vein, we saw a blood clot there,” he said.
More samples were collected for toxicology tests.
The exercise was conducted by a panel of seven pathologists.
The examination follows Munuve’s sudden death on Tuesday April 22, after a brief illness.
The process had attracted interest from political, medical, and investigative agencies.
