The 3 retired South African police officers who were hired by the opposition New Patriotic Party to train the party’s security unit and became subjects of controversy following BNI’s arrest—have all been deported to South Africa this morning.
It’s pretty interesting why and under what measure they were deported.
According to Graphic Online;

They were put on board South African Airways flight number 210, which departed around 9:26am Tuesday to Johannesburg.
Their entry visas have been revoked by the Ghana Immigration Service (GIS).
Officials from the GIS and security details from the Bureau of National Investigations (BNI), escorted the three to the aircraft, which was yet to be boarded by other passengers.

Apparently, South African security officials will pick that on arrival—what for, remains unknown.
The three — Major Ahmed Shaik Hazis (retd), 54; Warrant Officer Denver Dwayhe, 33, and Captain Mlungiseli Jokani, 45 — were arrested at the EL-Capitano Hotel where they had been based since arriving in Ghana.
