On Thursday members of the anti-gang unit arrested three men who were in possession of a CZ 75 pistol which had its serial number removed. Police also seized ammunition, including assault rifle ammunition, and drugs including tik and mandrax during the raid.
"The three suspects aged 24, 30 and 35, are due to appear in Khayelitsha Magistrate's Court once charged," said Western Cape spokesperson Capt FC van Wyk.
"Two of them are facing charges of possession of an unlicensed firearm, ammunition and drugs, while the other is facing a charge of possession of ammunition and drugs," he said.
"Western Cape provincial commissioner Lt-Gen Khombinkosi Jula has expressed his gratitude towards the SAPS members who have executed this breakthrough and strongly condemns the senseless killings in our communities."
Mbazwana is the third lawyer to be killed in Cape Town recently. Noorudien Hassan was killed at the end of 2017 and Pete Mihalik was slain in front of his children's school in Green Point last October.
