The underwater images show cracks in the color and impact marks suspected to have been caused by the anchor chain, according to the police in a press release.
The police have continued their investigations of the vessel, which is flagged on the Cook Islands and is believed to belong to the Russian shadow fleet. They have also interrogated the crew "under good cooperation" and seized hardware.
Earlier, the police discovered a several-mile-long drag mark after the vessel, which is believed to come from its anchor. The vessel is suspected of being behind the crime on the Estlink 2 power cable on Christmas Day. Three communication cables have also been destroyed.
The vessel's owner, a company based in the United Arab Emirates, wants the Eagle S released, according to a request submitted to the Helsinki District Court on Monday. According to the company's lawyer, the authorities have not explained the legal grounds for seizing and boarding the vessel, reports Euractiv.
Finland has seized a vessel, says lawyer Herman Ljungberg to Reuters.
The criminal suspicions are currently gross sabotage and gross telecommunications offense.
