Onlookers were shocked to spot a "large reptile" prowling around in London's Docklands.
One worried City worker took a photograph of what he thought was a crocodile near a sailing and watersports centre on the Isle of Dogs.
Ben, who works in Canary Wharf, said he was out for a stroll with a friend on his lunchbreak yesterday when he made the find.
He told News Shopper: “To our horror we spotted what appears to be some sort of large reptile.
"My colleague thought it might be a dinosaur but I corrected him that it looked more like a crocodile.
“ Nobody saw Brexit coming... so perhaps there is some sort of prehistoric Nessie-like creature living in the depths, or shallows, of Millwall Dock?"
Residents speculated on social media as to what the creature might be.
Thankfully the "crocodile" turned out to be nothing more than a pile of old rope.
Docklands Sailing & Watersports Centre manager Judi Sanders said: “This is quite funny although I am sure some people would be taken in by this and not want to come here.
She added: “It is rope, the water gets tested independently every other week.”
In April. footage emerged of a 'mysterious creature' moving through the depths of the Thames.
