Severn Trent Water says it is now investigating what caused a 12ft-deep sink hole to appear in the middle of a Mansfield street.
Police blocked off a section of Normanton Drive, off Eakring Road, this morning after a section of the road collapsed.
Nottinghamshire County Council investigated the hole, but have now passed responsibility onto the water company after suspecting the it was caused by a burst sewage pipe.
Severn Trent issued a statement saying: “The road has now been closed to make sure everyone is kept safe. At the moment, they can’t see if there is a problem with the sewer, so will have to do further investigations. We’ve got teams on site now, and they’ll continue to investigate through the night.”
The hole from the surface measured about a foot wide, but is 12ft deep and seven foot long underneath.
Jane Anderson, who lives on Normanton Drive, said: “It was a neighbour who spotted it, but it wasn’t there when we went out this morning at 9.30am.
“When you look into it, it looked like an underground cave, it looks like it’s been excavated.
“What’s worrying is that it looks like nothing is supporting the road surface. It’s frightening
“If the road had been covered in snow you would not have known it was there. This is a heavily-used road.”
