VIDEO: What lies beneath? Mystery hole complete with steps appears in couple's front garden '“ and nobody knows what it is

The hole, which measures around two feet by two feet, appeared when Emma James was mowing the lawn at her home in Kynaston Avenue, Stoke Mandeville.

It has steadily got worse, and her husband Kevin says he has been in contact with Aylesbury Vale District Council, Bucks County Council, utility companies and even the original company that built the house in 1984 to try to solve the mystery. But no-one is claiming responsibility for the hole, which appears to be more than two metres deep.

Emma, who works at Stoke Mandeville Combined School, said: “We’ve lived in the house for eight years and had no problems.

“But in November time I started to notice that there was a little bit of a dip in the grass.

“It’s getting worse, and nobody wants to know, we just need somebody to come out and have a look and tell us what it is and what we can do about it.

“Someone could fall down it. Over Christmas we had the cars parked on there so they could have gone in.

“We can’t even tell the depth of it, it’s a mystery.”

Emma and Kevin have enlisted the help of their local councillor, Marcus Rogers, in a bid to get the problem sorted. But in the meantime they are using two traffic cones and a piece of wood to make the hole safe.

Mr Rogers said: “I am appalled that this family have been treated so badly by the district and county councils.

“It’s time they stopped pointing the finger at each other and took some action.”
