Mediacare24 Holdings chief executive Michael (Mike) van Wyk.

WhatsApp chats, voice notes, and video clips presented before the Madlanga Commission of Inquiry on Monday have revealed what appears to be alleged drug dealing between Medicare24 Holdings chief executive Michael (Mike) van Wyk, attempted murder-accused tenderpreneur Vusimuzi ‘Cat’ Matlala and a third party whose name is yet to be revealed.

Matlala’s Tshwane Medicare24, which is embroiled in a controversial multi-million rand SAPS contract, is a franchise or subsidiary of Van Wyk’s Medicare24 Holdings.

Van Wyk was meant to testify before the Commission on Monday. His attorney, Sandy du Plessis, requested a postponement, saying her client suffered panic attacks and was admitted to hospital on Sunday.

The Commission approved the postponement, with the Commission’s chief evidence leader, Advocate Matthew Chaskalson SC, suggesting that he be allowed to lead the evidence, which Van Wyk would be cross-questioned on, so that the day of the proceedings is not lost.
