Finnish authorities released the cargo ship Fitburg, suspected of damaging an undersea cable between Helsinki and Tallinn, while one crew member remains in custody. The investigation continues with three other crew members under a travel ban. The vessel was detained on New Year's Eve after allegedly dragging its anchor along the seabed. Authorities are treating the incident as aggravated criminal damage. The situation is viewed in the context of heightened tensions and suspected sabotage linked to Russia.
