Finnish police said on October 19 that they had completed their crime scene investigation into the damage to a subsea gas pipeline between Finland and Estonia.
The Balticconnector pipeline linking Finland and Estonia ruptured earlier this month in what authorities said may have been a deliberate act of sabotage, cutting off the flow of gas between the two countries until April at least.
A gas pipeline and telecoms cable connecting the two countries were damaged on October 8. Helsinki is investigating the pipeline incident, while Tallinn is probing the cable incident.
Finnish police said in a statement that samples collected at the site of the damaged pipeline in cooperation with Finland's armed forces and coast guard would now be analyzed.
Meanwhile, Estonia says it will also probe the damage to a Baltic Sea telecommunications cable connecting the country to Sweden as part of its ongoing investigation into the Balticonnector rupture.
Sweden said on October 17 that a third link had been damaged. Estonia said on October 19 its probe would be expanded to include that incident.
