Police in Denmark say they detained a man and two women on suspicion of supporting the Islamic State group, in violation of the country's anti-terror laws.

Investigator Jens Moeller Jensen says 100,000 kroner ($18,000) were seized during Wednesday's raid.

Ali Daghim, of Palestinian descent, told the AP he sold some 20 car bumper stickers, each costing 50 kroner ($9), which he said had nothing to do with the IS group.

The 35-year-old Daghim denied supporting the extremists, saying the logo on the black-ribbon stickers — white Arabic text on a black background — is used by many Muslims, including the militant group.

They face preliminary charges — a step short of formal charges — for financially supporting a terrorist organization and face up to 10 years in prison if convicted.
