Colonel Leonard Hlathi said shops owned by foreigners were looted during and after the funeral of Wellington Hendrey Dube on Sunday.
Dube was allegedly shot dead by a Somali shop owner on February 25.
“Dube was on his way to school and walked passed a shop owned by the foreign national to see his fellow schoolmates who were standing outside the shop.
“The shop owner came out of the shop whereby an altercation ensued in which he allegedly accused Dube of being one of the people who committed robbery at his shop,” Hlathi said in a statement.
The shop owner allegedly beat Dube with his fists, Dube pulled a knife from his pocket and the shop owner shot him dead with a pistol.
He said police were still looking for the foreign national who had been on the run since the death of Dube.
The arrested people were expected to appear in the Kwabokweni Magistrate’s Court on Tuesday.
