As part of its ongoing investigation into the rupture that occurred on another telecom cable connecting Tallinn with Helsinki, Estonia said on Thursday that it would look into the damage on a cable that crosses the Baltic Sea and connects the nation to Sweden.

Investigators in Finland suspect that the breaking of a gas pipeline and telecom cable linking Finland and Estonia on October 8 was the result of intentional sabotage. Tallinn is looking into the cable incident, while Helsinki is looking into the pipeline issue.

On Tuesday, Sweden said a third link had been damaged at roughly the same time as the other two.

On Thursday, a spokesperson for the Estonian Prosecutor General said the Baltic country’s probe would be expanded to include both telecoms cable incidents, in a move showing a potential link between the two was being considered.

“The circumstances of the telecommunications cable connecting Estonia with Sweden will be investigated within the ongoing criminal proceedings,” the spokesperson told Reuters.
