The man is suspected of murdering a 23-year-old woman, who has been missing since June 30th in the western Swedish town, roughly 75 kilometres north of Gothenburg.
“We can confirm that on Monday we detained a Swedish man who was being searched for internationally by Swedish police,” Mariusz Sokolowski of the national Polish police force told the Aftonbladet newspaper.
“This occurred in the Swedish embassy in Warsaw. We came there at the request of the embassy.”
He added that the case was taken as seriously in Poland as it is in Sweden.
The 36-year-old suspect had been detained before in Sweden on suspicion of kidnapping, while two younger men were detained for aiding a criminal. He will be back on Swedish shores within ten days.
The hunt for the woman’s body has been extensive, involving police divers and hundreds of members of the volunteer Missing People organization. Her body is still missing.
