At least 23 police officers were killed by colleagues in the 20 months leading to August 2016, Deadly Force, a database by Nation Newsplex reveals.
That is equivalent to nine per cent of the 262 people killed by police during that period.
The only other group killed at a higher rate are suspected gangsters or robbers.
In the first eight months of 2016 the number of police officers killed by their colleagues had increased by 55 per cent over the whole of last year, according to a Newsplex review of the data.
In 2015, nine police officers were killed by their colleagues. That number is set to double this year if the current trend continues, given that 14 police officers had been killed by their colleagues as of August.
This number does not include police officers who have turned the guns on themselves after killing other officers or who committed suicide without killing their colleagues.
In August the National Police Service (NPS) formed a team to investigate the killings of police by their colleagues with a view to establishing the causes and also remedial actions
The largest number of officers killed in a single incident was seven. In the incident that happened on July 14 this year, Constable Abdihakim Maslam opened fire on his colleagues in Kapenguria with the Officer
Commanding Station (OCS) among the dead. The matter is still under investigation, but the rogue officer, who was also shot dead, is believed to have been radicalised by Al Shabaab. Maslam had served for about two and half years.
In August the National Police Service (NPS) formed a team to investigate the killings of police by their colleagues with a view to establishing the causes and also remedial actions.
The team, headed by the Director of Community Police at Vigilance House, Mr Aggrey Adoli, went round the country investigating cases and interviewed the officers.
The Newsplex analysis revealed some of circumstances related to the police killings included work rivalry, friendly fire, crimes of passion, terrorism and extrajudicial executions.
In most cases, the statistics show, junior officers shot their seniors. Grievances, including unfair deployment, transfers, and disciplinary action among others, have been cited.
