4 ISIS suspects arrested, weapons seized in Denmark, police say

Danish police seized weapons and ammunition in connection with the arrests of four people suspected of being radicalized by ISIS, Copenhagen police said Thursday.

The four were arrested near Copenhagen, police spokesman Mads Jensen said.

It was not immediately clear whether the suspects were actively plotting a terrorist attack.

The arrests and seizures mark the latest efforts by European authorities to crack down on terror in the wake of attacks Brussels, Belgium, and Paris.

ISIS claimed responsibility for both those attacks as it spreads terror from its epicenter in Iraq and Syria.

In February 2015, a man swore fidelity to ISIS leader Abu Bakr al-Baghdadi in a Facebook post before attacking a free speech forum featuring a controversial Swedish artist and then firing shots near a synagogue in Copenhagen. Two civilians were killed and five police officers wounded, according to Danish authorities.

Police tracked the gunman down and shot him dead. Authorities identified him as a 22-year-old man born in Denmark who'd been "well-known by the police for several criminal incidents."
