A Kenyan police officer has been arrested over the shooting of an unarmed civilian on Tuesday during protests in the capital Nairobi touched off by the death of a blogger in police custody, a police spokesperson said.

Outrage over the death of a Kenyan teacher and activist in police custody sparked protests in the capital Nairobi this week after doctors refuted a police claim that he had died in his cell from a self-inflicted head injury.

Kenyan police have shot an apparent bystander at close range during the latest protests over the killing of a blogger in custody earlier this month
