A lizard that was initially believed to be a Komodo dragon was spotted crawling through the sewers beneath the streets of Bangkok city.
Tourist John Hernandez, who happened to be in the area, managed to catch the lizard on video.
Hernandez said he was at a temple in downtown Bangkok when he heard people screaming. He then rushed over and managed to film the reptile as it crawled around beneath a pavement grate.
He wrote in the video's description that "people were screaming and pointing into the sewer".
"There it was. I got the video to prove it!", wrote Hernandez.
According to a report in UPI, a Reddit user suggested the animal could be a water monitor instead of a Komodo dragon, which are primarily found in Indonesia.
Redditor justcauseofit explained: "Komodos can eat half a goat whole, so dining on rats in the sewers would not be enough. They're extremely dangerous animals and would be taken far more seriously than folks in the video seem to."
Water monitor lizards can be found throughout Asia.
Metre-long monitor lizards have been spotted at housing estates in Singapore. In 2013, a monitor lizard was caught at a Yishun housing block lift lobby, and a photo of it was sent to citizen journalism website Stomp.
