Inspector General of Police Douglas Kanja has arrived at the Central Police Station, Nairobi, amid the planned protests by a section of activists.
Kanja arrived at the station accompanied by DIGs Gilbert Masengeli and Eliud Lagat.
They are expected to address the press in connection with the death of Albert Ojwang, who is said to have died by suicide inside the cells.
Kanja has already ordered the interdiction of several officers, including the OC,S pending investigations.
Ojwang, a teacher based in Voi, was allegedly arrested on Saturday in Homa Bay town over what authorities described as a "derogatory" post on X.
He had travelled to Homa Bay to visit family when he was picked up by police officers.
Ojwang was driven to Nairobi and booked at a police station for further questioning.
Police said he died by suicide after allegedly injuring himself while alone in a cell.
He was found with serious head injuries believed to be self-inflicted and was rushed to hospital, where he was pronounced dead.
“He was rushed to the hospital after what we think was an attempted suicide. He had injured himself in the head and was rushed to the hospital, where he died. He did not die here in custody,” Nairobi Central Police boss Stephen Okal said.
The body was moved to the mortuary pending an autopsy. Ojwang’s family has been informed and was expected in Nairobi to witness the post-mortem.
A team from the Independent Policing Oversight Authority (IPOA) is expected to join the probe into the incident.
