Hayners, who is also a suspect in a homicide case in the Wynberg magistrate’s court for a hit-and-run case in Lotus river which led to the death of a six-year-old girl and her nanny, was found in possession of an unlicensed firearm at the scene where the drugs were found.
Two cars were also seized during the raid.
Last week Zaynisa Alfoz, 45, to whom the storage facility was being leased, handed herself over to the Hawks.
Hawks spokesperson captain Philani Nkwalase said that Alfoz, Overmeyer, and Jonathan appeared in the Somerset West Magistrate’s Court on Tuesday on charges of drug possession.
All four suspects are expected to appear in the Somerset West Magistrate’s Court on Thursday for a formal bail application.
