The daughter of an elderly couple, found buried in their back garden, has been arrested on suspicion of their murders.

Susan Edwards, 55, and her husband Christopher, 57, were arrested at St Pancras International railway station in London on Wednesday evening, said the news agency.

Nottinghamshire Police have refused to confirm the identities of the pair under arrest, but it is understood that they are the daughter of William and Patricia Wycherley and her husband.

The couple, who are believed to have been living outside the UK, are being questioned in police custody.

It comes after human remains – thought to be that of Mr and Mrs Wycherley’s – were found at a house in Blenheim Close, Forest Town in Mansfield, Nottinghamshire, last month.

Police were led to the site following a tip-off.

The elderly couple moved to the address in 1987 and according to neighbours, disappeared in 1998.

Officers have said Mrs Wycherley is believed to have been born in Fulham, west London, and would now have been 79. Her husband would have been 100.

Police said bone analysis has shed further light on the remains.

One of the bodies is believed to be that of an elderly white man who was older than 60, well-built and around 5ft 8in.

The second set of remains is likely to be that of a well-built white woman, who was 40 or older and around 5ft 6in.

Although the cause of death has yet to be determined in both cases, the female remains have a “distinctive feature in their anatomy”.

Detective Chief Inspector Rob Griffin, who is leading the inquiry, said: “Bill and Pat, who would be 100 and 79 respectively if they were to still be alive today, were known to be quite reclusive.

“But with help from relatives and old friends, we are starting to build a picture of their lives and, more importantly, their movements in 1998, when neighbours say they simply disappeared.”
