Reports from state media indicate that Mzembi was taken into custody on Friday. He made a brief court appearance before the matter was postponed to today.
Before his arrest, Mzembi is said to have held a private meeting with President Emmerson Mnangagwa.
Mzembi fled Zimbabwe in 2017 following the ousting of long-time leader Robert Mugabe, and has been living in exile since.
Authorities have not yet disclosed the reason for his arrest, and it remains unclear what charges, if any, he is facing. Further developments are expected to unfold in court.
