Human rights activist Maina Kiai was detained at JKIA after immigration officials asked him for travel clearance.
He was due to catch a flight at 7.50am but the immigration people refused to stamp his passport.
The immigration supervisor at the airport Nancy Nganga didn’t say why Kiai needs clearance yet he isn’t a government official.
Recently, KHRC ran into trouble with state after the coordination board ordered its accounts frozen.
Kiai is a board member of the charitable organisation.
They obtained orders from a court stopping NGO coordination board boss Fazul Mahamed from executing the freeze order.
Later, immigration allowed him to leave.
