A high-ranking official - the alleged mastermind behind the killing of a top government anti-fraud and corruption fighter - has been arrested, police said yesterday.
The suspect was arrested on Thursday at work in Ngwelezane for his alleged involvement in the murder of relentless crime buster Thembinkosi Dlamini.
His arrest, police said, was kept under wraps because of the sensitivity around the high-profile murder.
Dlamini was shot dead in his office outside Empangeni three weeks ago when seven bullets were pumped into his body.
Superintendent Muzi Mngomezulu confirmed that the suspect was charged in connection with being the mastermind behind Dlamini's killing.
He said the suspect was arrested in his office - the same one where Dlamini was gunned down.
The man faces charges of organising two hitmen to kill Dlamini, a SA Social Security Agency (Sassa) manager of the Ngwelezane social development office.
Dlamini, who was deployed to root out fraud and graft at the second most corrupt office of the social development department, had no chance when the hitmen struck.
After the killing, MEC for social development Meshack Radebe, who assigned a specialised task team to probe the assassination, promised to bring the culprits to book.
"We expect more arrests. We have been informed that police are following strong leads," Radebe's spokesman Mandla Ngema said.
"This is a major breakthrough in the case."
Two weeks ago, two alleged hitmen were arrested in connection with the murder.
They appeared in the Empangeni magistrate's court and were denied bail. The third suspect, arrested last week, appeared in the same court on Monday with the two alleged killers.
They were again denied bail.
"I congratulate the security agencies for their good work done in arresting the suspects," Sassa chief executive Fezile Makiwane said.
"I hope justice will be done, and that the matter will soon be put to rest."
The department of welfare said the arrest was a major breakthrough in the investigation into Dlamini's killing.
"All those who were involved are going to be arrested," Ngema said.
