The remains of Sarah Mayhew, 38, were discovered in Rowdown Fields in New Addington, Croydon, last Tuesday.

The relatives of Ms Mayhew, from Croydon, have been informed of her death and are being supported by family liaison officers.

A 44-year-old man and a 48-year-old woman were arrested on Saturday on suspicion of murder and remain in custody, the Metropolitan Police said.

The two people detained were known to Ms Mayhew and police are not looking for anyone else in connection with her death, Detective Inspector Martin Thorpe added.

"My thoughts are with Sarah's family as they deal with this heartbreaking news," he said.

"No family should have to lose a loved one in such tragic circumstances, and we will continue to provide our support as our investigation progresses."

Police were called to reports of human remains found in the south London park shortly after 9am on Tuesday.

The remains were sent for urgent genetic analysis which confirmed them as human. A post-mortem then took place over the weekend.

Chief Superintendent Andy Brittain, Croydon's lead for policing, said officers will remain "visible and available" to the local community in the New Addington area.

"We repeat our thanks for the support and patience of the public, which has allowed officers to carry out important enquiries at the scene," he added.

Anyone with information that could help the investigation is being urged to contact the police.
