Swedish police officials say the arrest in Arctic Sweden of a man suspected of preparing "terrorist" crimes took place without violence.

National Police Commissioner Dan Eliasson says the late Thursday arrest was made in Boliden, a village in a large, snowy forest more than 600 kilometers (370 miles) north of Stockholm, by local police forces.

Eliasson says the man, whom officials won't name citing secrecy, and others are being questioned.

He told Sweden's public radio on Friday it was standard procedure to question other people "to find out more information about the suspected terrorist."

On Wednesday, Sweden had raised its terror alert to the second-highest level.

The case is not believed to be linked to the Paris attacks.
