Around 200 people have or will in the days be called for topping due to the assault and rape in Rågsved.

- Either they are called to a police station or we go out and try to get hold of them simply, says Anders Bryngelsson, press spokesman in the Stockholm region.

Last spring, two women were assaulted by a knife-armed man near the Rågsved metro station in southern Stockholm.

A 23-year-old woman was assaulted in a park area and later that night a 25-year-old woman, under knife threat, was forced into her apartment. However, the perpetrator left the scene because the woman's partner was at home.

Masked man

Almost three months later, on June 14, a woman was assaulted and raped by a masked man in the same area. Three weeks later, on July 7, another woman was assaulted and raped in Rågsved. The police have secured DNA from one of the rapes but received no hit.

"The people who are called to tops are not suspected of crimes, but they are one of several investigative measures that are taken to further investigate these serious crimes," Anders Bryngelsson, press spokesperson in the Stockholm region, said in a press release.

Everyone who is called will be allowed to submit a saliva sample for DNA analysis. According to the police, the test will only be used for comparison against the current case and then destroyed.

Noa has assisted the investigation

The police have been selected according to a number of criteria. Among other things, the National Operations Department's group for perpetrators profile went through the investigation material and presented a possible geographical profile.

Geographic profiling has been used as a method of investigation in Sweden since 2004 and, among other things, gave hits during the investigation of the so-called Hagaman in Umeå and during the search for the now murdered Peter Mangs in Malmö.
