Police in South Africa on Friday arrested more than 100 undocumented foreigners living in a house east of Johannesburg.

Home affairs minister Aaron Motsoaledi said Police arrested them following a tip-off and invited immigration officers along.

The group consisted of 98 Ethiopians and four Malawians in a house in Primrose, 14 kilometres (nine miles) east of Johannesburg.

Motsoaledi said the Ethiopian running the house had been a refugee in the country since 2019, having renewed his status four times.

“From what I can understand they are brought here to run the spaza shops (general stores) around the whole country” he added.

The home affairs ministry said it had found only four passports in the house with no South African visas.
