Trapped whale freed from 'whelk pots' in Start Bay

Footage of a daring whale rescue has been released by the RNLI.

Chris Lowe, from the British Divers Marine Life Rescue, can be seen hanging off the side of a boat, freeing the humpback whale from "a heavy line of whelk pots".

"Doris" the whale has been spotted in the area several times in the past few weeks.
