Security consultant and former Kenya Air Force commander Mwenda Mbijiwe has been reported missing.
His sister, Tamara Mbijiwe, told nation.africa that the Chief Executive Officer of Eye on Security Limited was last seen on Saturday as he left his house in Kileleshwa, Nairobi for their rural home in Meru.
"He left using a hired car and was last traced to Thika Road," said Ms Mbijiwe.
Mr Mbijiwe, an air defence control commander during his time in the army, is a popular consultant who has made several appearances on television talk shows to talk about security matters.
He is also an avid user of social media where he makes known his views on various issues.
