The charges involve an alleged hand grenade murder attempt and conspiring to kill a lawyer.
Security is expected to be tight, as an Anti-Gang Unit member has also been drawn into the case.
The Blue Downs Regional Court will hear a bail application on Friday involving controversial businessman Nafiz Modack and several other co-accused.
Modack, an alleged underworld kingpin, faces a raft of charges, including alleged gang activity, being part of a hand grenade plot against slain Anti-Gang Unit (AGU) detective Charl Kinnear, and a shooting at the home of Cape Town lawyer, William Booth.
For security purposes, Modack and his co-accused were moved for one consolidated bail application.
