A police officer is in critical condition after he was shot on the head in Kasarani, Nairobi by an unknown person.

According to a police report filed at the Sunton Police Station, Kasarani, the officer identified as Mohammed Happi was shot during an operation at the Hunters Stage in the same area targeting Public Service Vehicle (PSV) conductors operating without uniforms.
