STOCKHOLM (AP) — Swedish prosecutors have arrested a Syrian man on suspicion of terrorism for an arson attack against a Muslim group two months ago.

Prosecutors on Tuesday said they had filed a request to keep the man in pre-trial detention while they continue the investigation.

The 29-year-old man is suspected of committing an act of terrorism through an arson attack against what Swedish media described as a Shiite prayer room in the city of Malmo. No one was injured in the Oct. 11 fire.

The suspect has not been publicly named. His defense lawyer, Lars Edman, says his client denies the allegations.

Immigration officials say the man arrived in Sweden last year and received a three-year residence permit three days after the arson attack.

He was arrested on Saturday.
