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 specialist officers have been with Sarah's family to update them on the investigation and to continue to give them the best support we possibly can.

The news today that it was a Metropolitan Police officer who was arrested on suspicion of Sarah's murder has sent shockwaves and anger through the public and through the mat.

I speak on behalf of all my colleagues when I say that we are utterly appalled at this dreadful, dreadful news.

Our job is to patrol the streets and to protect people.

The investigation is large.

It's very fast moving, extremely determined.

We have had and continue to have hundreds of officers and staff working around the clock.

Sarah's disappearance in these awful and wicked circumstances.

I know our every family's worst nightmare.

Londoners will want to know that it is, thankfully, incredibly rare for a woman to be abducted from our streets.

But I completely understand that despite that women in London and the wider public perhaps particularly those in the area where Sarah went missing, we'll be worried and maybe feeling scared.

You should expect to see continued increased police patrols in the area as well.

Of course, as continued large scale investigative activity, please do report any concerns you may have whatever they may be to us, where you've been so impressed.

I'm very thankful for the public's support for the investigation in so many different ways, but in particular for sharing our appeals for information.

And we are deeply grateful to all those many, many people who came forward with information that has assisted us.

My thoughts tonight with Sarah, her family and her loved ones.
