Dlamini was arrested on Thursday afternoon. While police were yet to confirm his arrest, a source said Dlamini’s detention emanated from charges laid against him at the Dobsonville police station on Wednesday.
The case against Dlamini and Operation Dudula members had been opened by Soweto resident Victor Ramerafe, whose home was allegedly ransacked by Operation Dudula members on Sunday.
The group claimed to be acting on tip-offs from the community that drugs were being sold from Ramerafe’s home.
No drugs were found during the raid but Ramerafe said his property was damaged.
The EFF had backed Ramerafe in laying assault and theft charges against Dlamini.
Operation Dudula and other Dudula groupings have in recent weeks been in the spotlight over their campaigns which are mainly aimed at evicting illegal immigrants and removing them from informal trading spaces.
