The 26-year-old man is suspected of having led a smaller extortion gang that was behind a hand grenade attack on an apartment in Malmö this summer.
It is a serious extortion that this person is now detained for, says prosecutor Emma Carlsson to Sydsvenskan.
It is unclear when the man was arrested at Kastrup. According to the newspaper, he was deprived of his freedom in Denmark before being extradited to Sweden on Friday.
