NAIROBI (Reuters) -Kenyan police fired teargas at protesters in the capital Nairobi on Tuesday, a Reuters witness said, after the death in custody of a blogger cast a spotlight on alleged extrajudicial killings by security forces.

A demonstration over the death of blogger Albert Ojwang in police custody turned violent Tuesday with police in riot gear facing protesters in downtown Nairobi, Kenya. Several demonstrators were injured and property destroyed.

The blogger’s death comes almost a year after several activists and protesters were killed and abducted by Kenyan police during finance bill protests. The rallies led to calls for the removal of Ruto, who has been criticized for what some say is his authoritarian streak.
