The Swedish prosecutor's office has detained a vessel suspected of damaging a cable in the Baltic Sea, according to the agency's website.
"The vessel suspected of committing sabotage was arrested by the decision of the prosecutor's office," the statement said.
The investigation is led by Senior Prosecutor Mats Jungqvist.
