Kenyan police have shot and wounded a man brandishing a knife after he climbed into the grounds of state house in the capital, Nairobi, a police report says.

The police have said the man is a 25-year-old fifth year university student of mechanical science.

The man is said to have posted on his Facebook page on Sunday, 9 June, that he was on a religious mission to execute judgement on “thieves and their partners”.

He pulled out the knife after being challenged by officers at the gate where he climbed over. He was then shot and wounded on the left shoulder, the police report adds.

He has been detained and is being treated in hospital.
