Norwegian police seized a Russian-crewed ship on suspicion of being involved in causing “serious damage” to a fiber cable in the Baltic Sea between Latvia and Sweden.

Norwegian police have arrested a ship suspected of damaging a telecoms cable between Latvia and Sweden last weekend, according to the Norwegian public broadcaster NRK.

Swedish authorities have seized a ship over the “aggravated sabotage” of an undersea fibre-optic cable linking Latvia with a strategically important island in Sweden.
