Enköping resident Mia, who is actually called something else, wants to remain anonymous because she is ashamed of having gone on the scam.
- You feel stupid.
Usually I do not think I am a gullible person, but after this I felt it.
The man asked questions about Mia's sex habits and wondered if she was excited by the interview.
She has now reported the incident to the police.
Calling women throughout Sweden
Statistics Sweden has issued a warning for the man, who calls around to women all over the country with hidden numbers.
They urge everyone affected to make a police report.
- It has been going on from and to for several years.
We do not do research on sex habits and we never call from a hidden number, says Johannes Cleris, press officer at Statistics Sweden.
