Police Minister Bheki Cele has given the assurance that an alleged ring leader of the violence and looting in Gauteng and KwaZulu-Natal will be arrested today.
Three more people have been taken into custody and are expected to appear in court soon.
One of the alleged instigators was arrested on the West Rand.
Cele says they are determined to ensure that all those who are behind the criminal acts are brought to book.
More than 200 people have been killed in the week of violence and looting that followed the incarceration of former president Jacob Zuma.
