According to previous information from an anonymous source to the British shipping newspaper Lloyd's List, spying equipment was suspected to be on Eagle S - which is now denied.
"We have conducted extensive investigations of the vessel, and no findings of such equipment have been made", writes Criminal Commissioner Elina Katajamäki via email to Iltalehti.
Seven crew members are suspected of crimes and have been banned from traveling.
"A travel ban is a less extensive restriction of liberty compared to an arrest or detention, and it is important to ensure that the investigation is not compromised and that involved parties can be reached", writes the Central Criminal Police on their website.
More crew members, who are Indian and Georgian citizens, may be subject to travel bans during the course of the investigation.
Have Conducted Interrogations
The crew consists of 24 people. Those deemed relevant to the investigation have been questioned during the day, says Elina Katajamäki to Hufvudstadsbladet.
”The greatest interest is directed towards the part that was responsible for the vessel's journey during the incident”, she writes in an email to the newspaper.
Earlier on Tuesday, Finnish authorities released underwater images of Eagle S's hull.
Damage to the Hull
The images show cracks in the paint and damage marks suspected to have been caused by the anchor chain. Previously, the police have discovered a several-mile-long drag mark behind the vessel, believed to come from its anchor.
Eagle S, which is flagged on the Cook Islands and believed to belong to the Russian shadow fleet, is suspected of being behind a series of destroyed underwater cables between Estonia and Finland.
The criminal suspicions are currently gross sabotage and gross telecommunications offense.
