Libya blockade ship HMS Sutherland returns to Highlands 27 April 2013 Last updated at 00:10 A warship that cut short a visit to a Highlands port to join military operations off Libya was due to make a return visit to the town later. HMS Sutherland was in Invergordon in March 2011 to be given the freedom of the county of Sutherland. It left the port a day earlier than expected but at the time the Royal Navy would not comment on the reason why. About four months later the navy confirmed the frigate was diverted to the Mediterranean. HMS Sutherland and other warships blockaded Libyan ports as part of Nato operations against Col Gaddafi and his forces. Following the collapse of the Gaddafi regime, HMS Sutherland carried out anti-piracy work off the Horn of Africa. HMS Sutherland and its crew were expected to make their visit to Invergordon on Saturday. The Type 23 frigate has been involved in Exercise Joint Warrior. The international training has been taking place in the air, sea and land around Scotland. HMS Sutherland spent time in Loch Eribol in Sutherland on Friday.
