A 40-year old police officer was found dead in a bus parked at the Diplomatic police station in Nairobi after an apparent suicide.
Police said they are investigating the incident in which constable Martin Thairu was found dead in the bus on Wednesday evening.
He had a gunshot wound in his head. His AK47 rifle was found next to the body long after he had died.
Thairu is believed to have shot himself in the head through the mouth using his rifle in a bus parked at the station. The bus was being detained there as an exhibit.
Police said they had been looking for him since Wednesday morning when he failed to report to work. He is believed to have died on Tuesday night.
It was until evening hours when the body was discovered at the rear side of the bus.
Nairobi police boss Augustine Nthumbi said they are yet to know the motive behind the incident.
The incident comes days after another officer attached to Parklands Directorate of Criminal Investigations was found dead in his house after an apparent suicide in Kasarani area.
The officer was alone in his house near a supermarket in Kasarani when his body was discovered long after he had died out of suicide.
The Gigiri incident is the latest to affect police officers in a growing series.
Dozens of police officers have died of suicide in a trend that is attributed to stress at work.
As part of efforts to address the trend, police authorities have launched counseling services with the National Police Service Commission establishing a unit and staffed it to attend to their demanding situation.
The commission announced it had established the counseling unit, which will, among others, evaluate, design, and lead an outreach programme that helps prevent mental health and substance abuse.
