'Bownessie': the mysterious water 'monster' of Bowness
Sightings of a creature not dissimilar to the Loch Ness Monster have caused a stir in the normally quiet waters of the Lake District.
Local swimmer Tom Noblett, world record holder in fresh water swimming, thinks he was within feet of the creature whilst out for a morning swim.
Photographer Linden Adams also claims to have seen the creature and has captured it on camera.
The picture is now being analysed by experts in forensic visual computing.
Inside Out investigates the possible discovery of a new species of lake dweller, dubbed 'Bownessie', which some have likened to the Loch Ness monster.
Inside Out is broadcast on BBC One North West and North East & Cumbria on Monday, 20 February at 19:30 GMT. It is also available nationwide on the BBC iPlayer for seven days thereafter.
