The police do not want to comment on which countries the women who sold sex come from, but state that many of them come from poor countries in Europe.
"Most of what we were dealing with during the operation comes from vulnerable situations in poor countries, usually Europe," said police spokesman Ola Österling.
Eliot Wieslander, secretary general of the non-profit organization Doctors in the World, is working to try to help people from poor countries in Europe who sell sex in Sweden.
"You are often in a very vulnerable and vulnerable position, otherwise you will not come here," he says.
Tell the family
Wieslander says that it is usually possible to categorize the victims into two categories: those who come to Sweden to beg and who then end up in prostitution, and those who are forced here due to extreme poverty or through threats and blackmail.
-A woman we met had been subjected by two men to a very brutal rape filmed, threatening her that if she didn't sell sex to them in Sweden, the movie would be posted on the internet, and her entire family would see what "Whore" she was, he says.
The blackmail makes it more difficult for the victims to turn to Swedish authorities, as police in Sweden can rarely help them with the original threat in their home country, according to Wieslander.
- Some of them come from honorary cultures. If you are married and your partner finds out that you have had sex with someone else, it could ruin your life.
Stigma and shame
Men are also attracted and blackmailed to sell sex in Sweden. The group is in many ways easier to blackmail because the men usually sell sex to other men.
"There are women who come here to have sex for compensation, where their husbands know it and give their approval, while there is a much stronger stigma and shame for the men who have had sex for compensation," he says.
Doctors in the World want women and men to have access to subsidized care in Sweden to make it easier for society to help them, especially maternal care and care in the event of violence.
"In several of the cases we know of where people have been rescued from human trafficking, it has started with the fact that they have sought care for an injury or for an abortion," he says.
The organization also wants the police to make greater use of the consent law, since the prostitutes do not become targets through the usual sex purchase law.
-If you are a proprietor you get a victim status and can access help in different ways, otherwise you are only part of the target. It is central that we focus on the vulnerable instead, says Wieslander.
