“It has been decided he should continue to be detained,” Marit Åkerblom, the Östersund district court judge on the case, told AFP.
The man, whose name has not been revealed but who police said is in his 40s, was arrested Tuesday in accordance with an international arrest warrant issued via Interpol.
He is “wanted for war crimes”, Bertil Olofsson, who heads the international section of the Swedish criminal police, told AFP Wednesday, adding that the man was not a Swedish citizen.
Swedish news reports said the suspect is 44-year-old Zemir Kovacevic, a Bosnian and Croatian citizen.
“The way it works is that the government now has to inform the country that has issued the international warrant for him. They then have 40 days to request his extradition,” Aakerblom said, adding that if no such request was made he would be released.
The court and police did not say what exactly the man was suspected of, nor when and where the crimes were committed.
Swedish tabloid Expressen however reported he was being held in connection with war crimes committed in the Bosnian village of Sijekovac in March 1992.
