Moment volunteers rescued an exhausted humpback after it got caught on fishing nets

This the incredible moment volunteers rescued an exhausted humpback whale being dragged to the seabed by a lobster pot.

The 12m long adult was left fighting for its life after it got its tail caught on fishing gear off Orkney in Scotland.

The majestic mammal had spent at days - potentially up to a week - battling to keep its blowhole above water, but was fast losing its fight when volunteers arrived.
