The six accused - Angelo Beukes, Lee-Martin Daniels, Charl Kruger, Desmond Kruger, Mfaniseli Mkhehle and Gert Adams - face three charges of murder, the illegal possession of firearms, and the illegal possession of ammunition.
The group made a brief court appearance and put forward a formal bail application which will be heard next week.
Four of the six men - aged between 26 and 54-years-old - were caught by the Law Enforcement’s Marine Unit on Tuesday morning.
Officers noticed a suspicious Ford bakkie on Lukannon Drive and upon closer inspection found three bodies covered.
Mitchells Plain standby commander Colonel Dawood Laing said three of four men arrested on the beach were members of the 27s prison gang.
“Three of the suspects are from Eerste River and have gang tjappies, showing they are members of the 27 prison gang. The fourth suspect is from Mfuleni.
“The victims had both stab and gunshot wounds and appear to be between the ages of 30 and 40 years old.
“Two of the bodies had 26 prison gang tattoos...” Laing revealed.
According to a source, the fourth suspect is a Mfuleni mandrax merchant who supplies his area and Khayelitsha.
One of the victims is believed to have stolen pille from him.
The source told the Daily Voice that cops questioned the suspects, who piemped each other and gave officers an address in Forest Glade where the three are believed to have been murdered.
At the Forest Glade residence, police arrested another two suspects who were busy cleaning the house with Jeyes Fluid.
When cops searched the house, they also found two guns.
The matter against the accused is postponed until 9 April for bail information.
