Police sources claim that the man, identified as Brian Kibet based on his Facebook, is pursuing Mechanical Engineering at Jomo Kenyatta University of Agriculture and Technology. He's in his fifth year.

At the time of shooting on Monday evening, the student is said to have been armed with a knife. According to a police source, he's currently undergoing treatment at a Nairobi hospital.

"It's true there was a man shot and he's undergoing treatment," a police officer told Capital FM. "He had tried to gain entry to State House while armed with a knife."

The G squad officers from General Service Unit (GSU) are said to have shot and injured him of the shoulder. He's in a stable condition.

"He sustained shoulder injuries and he's being treated at the hospital. He's in a stable condition," another police source said.

State House and security officers are yet to issue a statement. Inspector General Hillary Mutyambai and DCI boss George Kinoti are said to have been briefed.

State House is out of bounds for members of the public unless one is armed with gate passes and permission. Unauthorized access is treated as trespass and security threat.

Usually, when such a incident happens, the Head of State is briefed by security officers. Previously, a man was shot dead in 2015 when he tried to access the highly secured place.
