Several vehicles from the police and Customs were parked next to an address in central Härnösand.

The Swedish Customs Service's press service cannot answer what the crackdown applies to during the evening when SVT calls.

- I can confirm that we are making an effort together with the police in Härnösand, otherwise pre-trial confidentiality prevails, says Martin Höglund, press secretary.

More information about the effort and its results can possibly be provided on Friday, according to Höglund.
