Cleaning up operations are under way at the old drive-in site in Durban where undocumented foreigners were temporarily located.

KWAZULU-NATAL authorities have intensified security measures across the province amid protests against illegal immigration, while eThekwini Municipality has begun clearing and rehabilitating the Durban Drive-In site following the completion of the voluntary repatriation process involving undocumented Malawian nationals.

The provincial government this week said law enforcement agencies had arrested five suspects accused of breaking into a tuck shop in Woody Glen, near Hammarsdale, as officials moved to prevent criminal activity linked to demonstrations taking place across the province.

KwaZulu-Natal Premier Thamsanqa Ntuli commended law enforcement officers for the swift arrests and warned that authorities would not tolerate lawlessness under the guise of protest.

"We acknowledge and respect that civil society has the right to protest and voice their concerns. However, we urge all those participating in today's marches against illegal immigration to do so within the prescript of the law," Ntuli said.
