Enoch Motsepe, 32, was denied bail in his last appearance in November.
In addition to kidnapping he faces charges of extortion and robbery with aggravating circumstances.
Four men allegedly entered the Bedfordview, Johannesburg, home of Ali Haji, from Tanzania, claiming they were police officers, on October 28. They took jewellery worth about R150,000, a BMW, and a cellphone. They kidnapped him and demanded a R100,000 ransom from his family.
Motsepe was arrested after allegedly collecting the ransom at the Caltex petrol station on the N1 highway in Midrand.
Police shot and wounded hip hop singer Khuli Chana when he allegedly failed to stop at a roadblock they had set up at the petrol station’s exit in an attempt to catch the kidnappers. Police were still searching for three others in connection with Haji’s kidnapping.
