Detectives searching for missing British woman Sarah Everard have found what appear to be human remains in a woodland in Kent, south-east England.
Police Commissioner Cressida Dick says it is still too early to confirm the identity of the body.
Sarah Everard, 33, has been missing for a week, with the Daily Mail reporting she "vanished into thin air".
A police officer has been arrested in relation to the case, facing charges of kidnapping and murder.
"This evening, detectives and search teams investigating Sarah's disappearance have found very sadly what appears to be human remains," Dame Cressida Dick, the head of London's Metropolitan Police says.
"The discovery was made in an area of woodland in Ashford in Kent. As you can imagine, at this early stage we are not able to confirm any identity, and indeed, that may take us some considerable time."
The marketing executive was last seen leaving a friends house in south London on March 3.
The suspect, 48-year-old Wayne Couzens, is a father of two children and also facing a separate indecent exposure charge.
A 39-year-old woman was also arrested at the same address for allegedly assisting an offender.
"The news today that it was a Metropolitan Police officer arrested on suspicion of Sarah's murder has sent waves of shock and anger through the public and through the whole of the Metropolitian Police," Police Commissioner Dick says.
"The investigation is large, fast moving and very determined. We have hundreds of officers and staff who have been working around the clock."
