Pretoria is a major destination point for trafficking of sex slaves within South Africa.
This has been revealed by the International Organisation for Migration (IOM) which has completed a six-month study into trafficking within South Africa's borders.
The report: No Experience Necessary; The Internal Trafficking of Persons in South Africa, was released last week.
It will be used as a basis for further research into trafficking in South Africa and to help civil society and government come up with comprehensive plans to assist victims and combat trafficking syndicates.
Funded by the United States Agency for International Development (USAID), the document reveals reasons behind trafficking and who the victims and perpetrators are, as well as the routes used by trafficking syndicates.
Previous research into South Africa and trafficking focused only on the aspect of external trafficking, where the country is used either as a destination, supply or transit region.
The latest report reveals that all forms of trafficking occur within the country with Pretoria and Bloemfontein ranking high on the list of destination points when it comes to the trafficking of sex slaves.
For the fourth year in a row South Africa has been placed on a special watch list for countries which the US State Department, which releases annual reports on trafficking persons, considers as unable to show efforts to meet the minimum standards required for the elimination of trafficking.
The research saw 224 people consulted, of which 108 revealed they were directly aware of trafficking in their communities.
The report revealed that those at greatest risk to trafficking in South Africa were black and coloured women younger than 20, followed by women aged between 21 and 30.
According to the document, the Eastern Cape was the greatest target of trafficking syndicates.
The report states: "Victims are often recruited with job offers through either a newspaper advert or friends or neighbours, who make the promise of a new life and money."
The report stated: "When it comes to sexual exploitation both girls and boys are vulnerable with boys often being used in pornography."
Classifying recruiters the report revealed that both men and women involved, with the majority aged between 31 and 40 and being either black or coloured, were paid between R250 and R3 500 per victim.
Most recruiters are known to the victims and are either friends or relatives.
"Organised crime is the biggest driving force behind trafficking with the primary motivating factor behind trafficking being money followed by the need for cheap labour," states the report.
Most syndicates operate out of Pretoria, Cape Town, Durban, Bloemfontein and Port Elizabeth.
Laura Bermudez, the report researcher, said such research was vital because of the extent and nature of trafficking which occurred in South Africa.
