He was in bed alongside his young child and wife, but they were not hit.The murder is believed to be connected to several killings and shootings which have recently played out in Cape Town as an underworld battle over the nightclub security industry and illicit drug trade intensified.In November, a cache of weapons, including ammunition, grenades, firearms and two military radios, were discovered at a storage facility in Kraaifontein and a residential property connected to the Breet brothers. Magistrate Bawa postponed the matter to February 15 and 21 for a formal bail application. The men remain in custody.
