Is that a crocodile in the River Thames?

A large 'crocodile' appeared to be prowling around in London's Docklands - and a worker on a lunch break managed to get a snap of the 'creature'.

A city worker, called Ben, took a photograph of what he believed to be a crocodile near a sailing and watersports centre on the Isle of Dogs.

The picture was shared on Twitter, and had people scratching their heads as to what it was.

Speaking to the News Shopper, Ben said: "While circumnavigating Millwall Outer Dock we passed the Docklands Sailing and Watersports Centre, where there were children enjoying a paddle in canoes.

"Then 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.

"Having said that nobody saw Brexit coming so perhaps there is some sort of prehistoric Nessie-like creature living in the depths, or shallows, of Millwall Dock?"

However, the terrifying "reptile" actually turned out to be a piece of rope.

According to the Evening Standard, Docklands Sailing & Watersports Centre manager Judi Sanders said: "It is rope, the water gets tested independently every other week.

"This is quite funny although I am sure some people would be taken in by this and not want to come here."

Back in April, a mysterious object - or creature - was spotted 'swimming' in the River Thames near the 02.

The video was taken by a passenger on the Emirates Air Line cable car, and the caption read: "This was on the cable car in Greenwich yesterday. something huge was moving under the water and then briefly surfaced. Are there whales in the Thames?? Or is it some weird submarine?"

Well, whatever it was, it definitely wasn't a crocodile.
