South African Airways (SAA) has suspended its acting chief executive, Vuyisile Kona, after he took over at the helm of the carrier less than two months ago.
A statement by the flag carrier says Kona was placed on "precautionary suspension" on 11 February after "certain allegations" came to the attention of the board of directors.
An investigation has been initiated, but the airline says that the board has not yet determined the "veracity" of the allegations.
Nico Bezuidenhout, chief executive of SAA's low-cost subsidiary Mango, has meanwhile taken over responsibility for the entire group's operations.
Kona became interim chief executive in December shortly after predecessor Siza Mzimela stepped down. The airline had planned to make a permanent appointment in early 2013.
A recruitment process is underway and should be completed by the end of March, SAA confirms.
