Danish police said Sunday they had arrested a man on suspicion of torching a mosque in Copenhagen earlier in the day, AFP reported.

“At 11:31 a.m. (0931 GMT), the police were informed that a man had started a fire by throwing a flammable liquid … at the Muslim center,” a police statement said.

The fire, which caused only superficial damage to the outside of the building, was quickly contained, police said.

The suspect, who was born in 1980, will appear in court on Monday, according to AFP.

The religious association whose members worship at the mosque, denounced the fire as “an act of terrorism” on its website.

This act “was likely the result of political and religious motives… As tragic at it is, it unfortunately does not surprise us,” the center said.

Since February, when a young Dane of Palestinian origin shot dead a filmmaker and an unarmed Jewish security guard outside a synagogue, Denmark’s Muslim community has feared being viewed with suspicion.

Out of Denmark’s population of 5.7 million, nine percent are foreign-born, of whom some 296,000 originate from “non-Western” countries, official statistics show.

In June, the anti-immigration Danish People’s Party became Denmark’s second largest party, securing 21.1 percent of the vote, its highest score ever.

Omar El-Hussein, the terrorist who killed two people in the deadly twin attacks in Copenhagen, had been identified  as a man “a history of violent crime” who had only been freed from jail two weeks before the attacks.

A Lebanese website reported that he was of Palestinian Arab origin and that his parents had resided in a camp for “Palestinian refugees” in Lebanon before moving to Denmark.

The head of Denmark’s intelligence agency stepped down in May as an investigation criticized parts of the police response to the deadly twin terror attacks in Copenhagen.

His resignation came hours before the publication of a police report that revealed it took almost four hours from the moment El-Hussein shot dead a filmmaker outside a cultural center, until police were deployed outside Copenhagen’s main synagogue, where a Jewish man was later killed.
