Nigerian pirates have freed four seafarers kidnapped last month from a reefer.

Lithuania’s deputy chancellor Rimantas Vaitkus said the men were released on Friday, according to the ELTA news agency.

They were taken from the 152,884–cbf Solarte (built 1982) off Port Harcourt on 19 October.

The vessel’s owner has said all the men were unharmed.

 “They are supervised by doctors. We will return them home once it is possible.
