A truck cabin that was swallowed by a sinkhole in Japan two weeks ago has been located in a nearby sewer pipe, authorities say.

Drone images suggest that a human body is inside the cabin, but it is unclear if it is that of the truck’s missing 74-year-old driver.

The sinkhole, which now measures 40m (131ft) in diameter, opened at a road intersection in Yashio city near Tokyo. It is believed to be caused by a sewer rupture.

Search teams are unable to enter the 5m-wide pipe due to continuous water flow and high levels of hydrogen sulfide or sewer gas, officials said.
