Since detective Oupa Matjie was fatally shot during a police operation in the Diepsloot in January, there have been heightened tensions over safety concerns in the area.
Some residents have blamed undocumented migrants for Matjie's murder and for the crime in the area.
There has also been a series of police raids on undocumented migrants in Diepsloot.
Over the past week, 702Breakfast has spent some time in the area engaging with the community and hearing its grievances.
Bongani Bingwa speaks to Home Affairs Minister Dr Aaron Motsoaledi on what is happening in the township.
Among the people that were arrested in Diepsloot, 100 were foreign nationals and 77 of them were undocumented. When you are found to be undocumented, you don't just get deported, you have to appear in front of a magistrate who must confirm that the immigration officers are right and once they say so, you are taken over to Lindela.— Dr Aaron Motsoaledi, Minister - Home Affairs
He says the problem is that most people do not understand what undocumented means.
If a foreign national comes into the country and say they are seeking asylum status, you cannot stop them provided they will appear at the nearest refugee centre. The people we call undocumented are those who are not on the national population register.— Dr Aaron Motsoaledi, Minister - Home Affairs
