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.

Swedish prosecutors have decided to release a vessel belonging to a Bulgarian shipping company after ruling out initial suspicions that sabotage caused damage to an undersea fiber-optic cable between Sweden and Latvia.

Authorities in northern Norway released a vessel that was suspected of the latest data cable breach in the Baltic Sea, saying no evidence had been found linking it to the incident.
