Johannesburg--Police in Johannesburg have detained a number of foreigners after raids on buildings in the city.
South Africa's high court has temporarily prevented the deportation of more than 300 undocumented migrants.
Rights activists have criticised the arrests of more than 700 suspected illegal migrants following recent deadly xenophobic violence.
Police say they made the arrests during crime prevention operations.
The authorities have been under pressure to both bring an end to the attacks on foreigners and to introduce tighter immigration controls.
The African migrants detained at the Lindela repatriation centre, 25km (15 miles) west of Johannesburg, were due to be deported on Wednesday, reports the BBC's Nomsa Maseko.
They had been arrested over the past few weeks during night time raids in and around Johannesburg.
But their deportation has been halted for at least two weeks after the organisation Lawyers for Human Rights went to the Johannesburg High Court to prevent it from taking place.
