“Last night, 29 January 2015 at about 7:30pm four Ethiopians were in their shop at Bhamshela area at Nsuze when they were attacked by four armed suspects,” said Major Thulani Zwane in a statement.
“Three of the foreigners were shot and wounded and the fourth was badly assaulted by the suspects.”
The attackers fled with an undisclosed amount of money.
The injured victims were taken to hospital.
A case of attempted murder and business robbery had been opened.
Provincial commissioner Lt-Gen Mmamonnye Ngobeni appealed to people to approach police with information about the suspects, he said.
Last week violence, labelled by some as xenophobic, and looting of foreign-owned shops spread from Soweto to Kagiso on the West Rand, Sebokeng in the Vaal, Eden Park in Ekurhuleni and Alexandra, north of Johannesburg.
This was allegedly sparked by the shooting of 14-year-old Siphiwe Mahori in Snake Park, Soweto, last Monday. Mahori was allegedly part of a group trying to rob a Somalian’s shop.
Somali national Alodixashi Sheik Yusuf has appeared in court charged with Mahori’s shooting. He will return to court on February 4.
At least nine people have been killed following the shooting of Mahori.
Over 180 other people have been arrested in connection with public violence and possession of stolen property.
