MURMANSK, January 9 (RAPSI) – Negotiations concerning the release of Russian trawler ship “Oleg Naidenov,” which was detained by Senegalese authorities, failed to take place on Wednesday as previously scheduled, RIA Novosti reported Thursday.

“Still no official charges [have been] filed, and the meeting was called off without any explanation,” the agency quoted director Yuri Parshev of Phoenix, the company that owns the ship, as having said.

Parshev noted that it is not yet clear why the negotiations failed to transpire.

He added that the ship’s captain requires medical assistance, but was not permitted to see a doctor.

The Russian-flagged Oleg Naidenov was detained by Senegalese border guards on January 4 with 62 Russians and 23 Bissau-Guinean crew members on board. After its detention, the ship was transported to the port of the Senegalese capital of Dakar, where it remains thus far.

Senegalese officials threatened the ship's owners with a fine of $800,000 for illegal fishing.

The ship’s captain and several crew members complained of physical abuse by Senegalese border guards. Guinea-Bissau detained several Senegalese fishing boats on Monday in alleged retaliation against the detention of its nationals, who remain on board the Oleg Naidenov.

Russia’s Federal Fisheries Agency said earlier that the negotiations failed because of an alleged Greenpeace intrusion.
