A South Korean court has handed down jail sentences to five Russian seafarers and an owner for trying to leave port without permission.

The 5,000-dwt cargoship Palladiy (built 1984) hit the headlines last year when four crew were arrested for allegedly "resisting authorities."

The Sputnik news agency cited Russia's Korean consul Roman Bykov as saying the owner of the vessel was jailed for two years and fined, while the captain received a one-year term and a fine.

Three more seafarers were handed 10-month sentences, while a suspended term of 10 months was imposed on the senior mechanic.

The men have a week to appeal.

TradeWinds has previously reported that Palladiy has been in South Korea for about four months for repairs. The bill had allegedly not been paid.

A court had issued an arrest order for the vessel, which was detained by Busan port in June over wage arrears.

A Russian crew union said the owner had since paid most of the wages.

The owner is listed as Far Trans of Vladivostok, which could not be contacted.
