Loch Ness Monster expert writes sighting 'manual'

Key points

• A Loch Ness Monster expert has written a guide on how to spot the creature. Adrian Shine, who founded the Loch Ness Project, says the monster exists and has explained how it can be seen in his new book.
• He believes Loch Ness lacks enough nutrients to support a large beast. He argues most sightings are wakes from large boats, which he links to the Caledonian Canal, built in the early nineteenth century.
• Broadcaster Robson Green said the expedition could neither prove nor disprove a creature's existence.
