This is the shocking moment a man standing at a bus stop suddenly disappeared underground when a sinkhole opened up in the pavement underneath him.
The incident was caught on CCTV cameras in the city of Yaroslavl in north-western Russia's Yaroslavl Oblast region.
The 51-year-old man, whose name has not been released, was standing on the pavement, close to a bus stop, when a small sinkhole opened up underneath his feet.
He immediately plummeted into the deep hole, disappearing from sight, much to the surprise of eyewitnesses who rushed to the scene to see what had happened.
The man was injured in the fall and unable to get out of the deep hole without assistance.
Fortunately, police officers were nearby and were quickly on the scene to help the man back to the surface.
Paramedics treated him at the scene and then rushed him by ambulance to a nearby hospital for treatment to a leg injury. He was later allowed to go home.
Local police spokeswoman Marina Kokueva said: "Police officers helped the man. He ended up with an injured leg."
The sinkhole was reportedly caused by steam from an underground heating pipeline which had weakened the ground underneath the pavement.
Netizen 'Sukhov' said: "In any other country, the man would have become a millionaire after suing the town hall, in this country he is only lucky to be alive."
And 'Olga Lapshova' added: "I wonder why the pavement fell down? Was it an omen from hell?"
Yaroslavl is one of the so-called Golden Ring cities, a group of historic cities north-east of Moscow, that are among the most picturesque in Russia.
The historic heart of the city, located at the confluence of the Volga and the Kotorosl Rivers, is a UNESCO World Heritage Site.
