The murder case of Pitch Black Afro's wife moved to Johannesburg Magistrate's Court on Thursday morning.
While police confirmed the arrest and that a murder inquest had been opened on the suspect could not be identified until his appearance this morning.
"There was an inquest opened but we changed that to murder. The suspect is being detained at the Yeoville police station and will be appearing court (today)‚" SAPS spokesperson Lungelo Dlamini told Sowetan.
The case was initially expected to be heard at the Hillbrow Magistrate's Court but it was moved to Johannesburg at the 11th hour.
News of Catherine's death was received with sadness on social media but the exact causes surrounding her death are not yet clear.
Catherine and Pitch Black Afro‚ real name Thulani Ngcobo‚ have been together for more than two decades.
The rapper's fans were introduced to Catherine after he wrote a song about her in the 2000's.
Sowetan further reported that it was initially believed Catherine died of natural causes‚ however a pathologist in the case found the cause of death to be unnatural.
Catherine apparently died at a B&B in Yeoville on New Year's Eve.
