Rushdien Abrahams, 45, made an appearance at the Mitchells Plain Magistrate's Court on Tuesday where he is facing drug-related charges.
Abrahams and a woman were arrested two weeks ago at a house in Westridge after police received a tip-off.
Police confiscated R300 000 worth of drugs including, tik, heroin, mandrax and ecstasy, as well as R200 000 in cash and two plastic sealers and a silver scale.
Sources say Abrahams from Westridge has a clean police record and formerly worked at an insurance company.
The matter was postponed to 20 March for his formal bail application.
Abrahams is currently in custody at Pollsmoor Prison.
Murphy and his six co-accused are currently on trial at the Cape High Court and are facing 229 charges including racketeering, drug dealing and money laundering.
Two weeks ago, the investigating officer, Captain Nadine Britz, testified that one of their witnesses had been communicating with one of Murphy’s drug runners while the trial was underway.
Britz said she had been called to the house where Abrahams said he was willing to speak to her, and showed her a Whatsapp conversation between him and the second State witness.
The woman was arrested at a drug warehouse in Lotus River and told police she had been packing drugs for Murphy.
Britz said Abrahams had been to every court appearance of Murphy since his arrest.
