He posted this message on his Facebook page saying he was stopped from travelling to South Africa to see his doctor.
He wrote:
I have been refused exit at Kenneth Kaunda International Airport to be attended to by the Doctor in South Africa, despite the courts authority.
The Doctor will be out of hospital for 21 days from tomorrow, therefore, if I’m not attended to tomorrow then my being attended to, will delayed for a further 21 days.
Instructions were made to the immigration department, not to allow me board the aircraft and my luggage offloaded too.
