Elisa’s data cable between Helsinki and Tallinn was damaged on Wednesday, according to the Finnish telecom firm.
According to a police statement, the Border Guard located a vessel suspected of causing the damage. Finnish authorities took control of the ship as part of a joint operation.
The suspected vessel was intercepted by the Border Guard patrol ship Turva and a helicopter in Finland’s exclusive economic zone, while the cable damage reported by Elisa is located in Estonia’s economic zone.
The police have consulted the National Prosecutor’s Office, which has issued a prosecution order.
Police are investigating the incident as aggravated criminal damage, attempted aggravated criminal damage and aggravated interference with telecommunications.
Last Christmas, an oil tanker called Eagle S dragged its anchor along the seabed, damaging several undersea cables between Finland and Estonia. The captain of the vessel claimed the incident was accidental.
Following a trial this past autumn, Helsinki District Court said it lacked jurisdiction in the case.
At 1:00pm on Wednesday, Finnish President Alexander Stubb said in a post on social site X that the country "is prepared for security challenges of various kinds, and we respond to them as necessary.
Or, it’s time to just stop allowing any shipping traffic to or from St Petersburg. If Russia keeps using civilian vessels from there to perform military acts of sabotage then it seems perfectly reasonable to stop allowing any vessels to travel to or from there. Any ships bound to or from that port need to travel through another countries teritorial waters to access the ocean and at this point they would be well within their rights to stop allowing those ships to travel through their waters. Enough is enough. Russia can either quit their shit or stop having a useful port in St Petersburg.
