According to the Finnish Border Guard, a ship believed to be behind the cable break has been identified. The ship had its anchor chain in the water and has been seized.
The damage was discovered on New Year's Eve morning in Estonia's exclusive economic zone.
The incident is being investigated on suspicion of causing serious damage and of seriously disrupting postal and telecommunications traffic, according to Hufvudstadsbladet.
The case is being investigated by the police and other authorities.
The cable is owned by Finnish telecom company Elisa, police said in a statement. The ship suspected of being behind the cable break was located by the border guard vessel Turva and a helicopter in Finnish waters.
According to Iltalehti, the seized ship is the Fitburg, which sails under the flag of Saint Vincent and the Grenadines.
The Attorney General has announced an indictment in the case. Finnish President Alexander Stubb announced that the authorities are monitoring developments.
