Finnish authorities on Sunday released a tanker held since Christmas amid suspicion it was involved in sabotaging underwater cables in the Baltic Sea.

The 74,000-dwt Eagle S (built 2006) was seized by Finnish forces and detained in the country’s territorial waters, with several crew members barred from returning home. The vessel’s passage coincided with a break in the Estlink 2 power link between Finland and Estonia, as well as damage to other cables.
