A fisherman told last night about the one that got away – a suspected Russian submarine which became entangled in his nets after it strayed inside British waters in the North Sea . Angus Macleod , 46 , was fishing for haddock and skate when he became convinced that a hostile vessel was caught up below his boat Aquarius . The submarine attempted to free itself , taking the 65ft vessel and his two-ton catch with it . Angus MacLeod ( pictured ) a fishing boat skipper , has lodged an incident report with the Maritime and Coastguard Agency and the Marine Accident Investigation Branch following the unusual occurence . Mr MacLeod was told that submarines were operating in the area when the incident occurred ( file picture ) Mr Macleod , whose account is being examined by the Marine Accident Investigation Board , said : ‘ Suddenly a force beneath our boat dragged the nets from behind us to in front of us . It was very powerful because the nets were full of fish and very heavy . ‘ The submarine was then ahead of Aquarius and heading on a northerly bearing towards international waters and bringing our nets along behind it . Only a submarine could have done this – it was a clear , still night and there were no other boats around . ‘ Had the submarine headed for deeper waters we might have sunk with it , but I don ’ t want to dwell on that . 'We were eventually cut loose when the 150ft-long dog rope , which attaches the nets to the ship , wrapped itself around Aquarius ’ s propeller and got ripped apart . We were then able to sail back to port. ’ Mr MacLeod says he suffered around £10,000 in damage and loss of earning due to the damage to his boat . Mr McLeod said following the incident : ' I 've been at sea for 30 years - and between the five of us there is 110 years experience - and in our collective times we have never experienced anything like that ' Mr Macleod , a fisherman for 30 years , never saw the submarine but is convinced that such a vessel caused the incident . It follows an upsurge in covert operations by the Russian navy in the waters surrounding the British Isles and patrols on the periphery of UK airspace by Russian aircraft . He added he was told by the coastguard that there was no Nato submarine activity in the area where the incident took place . The Ministry of Defence said it did not comment on submarine operations , while Foreign Office sources suggested they would consider the outcome of an MAIB investigation before making any approach to the Russian Embassy . The incident caused damage worth £10,000 and lost fishing time . Mr Macleod added : ‘ If you give me the address , then I ’ ll send the bill to Moscow . ’
