Police in Durban have sent a clear message that they will not tolerate any illegal activity during the festive season.
This comes after the arrest of 30 prostitutes and 20 people for alleged drug dealing in Durban's Point area since Monday.
The women were arrested as the police were conducting Operation Hotspot. Superintendent Muzi Mngomezulu said the arrests were just the beginning, as more operations will be conducted throughout the festive season.
He said some women were caught "conducting illegal business" and some even tried to "attract" police officers and were arrested.
The officers also apprehended alleged drug dealers during the swoop.
The swoop concentrated on the escalating drug trafficking within the central business district.
"These operations were conducted by means of entrapment, search and seizure.
"Two South Africans, three Nigerians and one Tanzanian were arrested for dealing in cocaine to the street value of about R11000," said Mngomezulu.
During the arrests, police used the Morpho Touch machine - a small machine that can link a person to a crime he committed but was never arrested for.
Thrity-nine illegal immigrants were also arrested, including 19 Tanzanians, two Nigerians and one Zimbabwean.
The Morpho Touch machine used during the operation connected four South Africans for various crimes, such as possession of dagga in February last year at Durban Central area, theft at the Amanzimtoti area in May last year, possession of a house-breaking instrument in October 2004 in the Malvern area and for domestic violence at the Point precinct.
Three motor vehicles were also recovered at an estimated value of R180000.
"We would like to warn all criminals out there that we are on their heels," Mngomezulu warned.
