The Swedish Economics Crimes Bureau and the police carried out raids last Tuesday in different suburbs of Stockholm in relation to money laundering, believed to have been aimed at financing terrorism, said Säpo in a press release.
According to information provided to the Dagens Nyheter newspaper, the suspicion involves the sending of money to Syria, possibly to the militant movement Islamic State (IS). Four people, three men and a woman, are sitting in custody. Prosecutors have until Friday to formally arrest or release them.
The head of Säpo, Anders Thornberg, would not go into the case, but did say to TT:"I take very seriously that terrorism is financed from Sweden."
