Two students in Lough Foyle, Ireland who were making a film for college think they may have captured footage of something that looks like the Loch Ness Monster. Conall Melarkey posted a video to YouTube with the following description: "Was shooting in Lough Foyle when this thing went past us. It was massive. Really don't know what it was. There have been whales in the Lough before so maybe that's what it was but Matthew was closer than we were and says it was no whale. Looks like we have our own Loch Ness Monster?! Any experts out there"?
