It has now emerged that the embattled Ruaraka Ex-police chief who has been handed a death sentence was a violent man.
Shocking witness accounts reveal Mr Mutua had the habit of hitting detainees unconscious, and dragging them into the cells.
Fateful day
On the fateful day, a report was received at Ruaraka Police Station at around 10pm, according to police constable Jonathan Chivatsi, who was manning the report office.
Mr Manyara reportedly refused to enter the cells, prompting the officers to inform the OCS, who at the time was at the police canteen situated within the station.

The same day, Mr Victor Kioko was brought in on allegations that he had refused to settle a bill for drinks taken at Lexx Bar, also in Ruaraka.
The court heard that Mr Kioko was escorted to the station by two staff members of the bar, identified as Doreen and Abu.
At the report desk, he found the OCS, armed with a metal rod, landing blows on a helpless Manyara.
He identified the OCS because he knew him from past engagements and called out his name.
Beat senseless
On hearing his name called out, the police boss made a swift turn, punched Mr Kioko in the face and, using the metal rod, landed several strikes on him.
Mr Kioko fell to the floor. On the orders of the police, he was dragged into the cells.
