Further tests are needed to find the cause of death of a girl who was found dead in a house in Woking. 

The 10-year-old, who has been named locally as Sara Sharif, was discovered in Hammond Road at 2.50am on August 10.

A post-mortem examination performed on August 15 found the cause was “still to be established”, detective superintendent Mark Chapman from the Surrey Police and Sussex Police major crime team said.

Officers are looking to question three people over Sara’s murder who were all known to her.

Police believe the trio left the country on August 9, a day before Sara’s body was discovered.

It was revealed that no other people were present at the property when Sara’s body was found.

Mr Chapman told reporters at a media briefing at Surrey Police headquarters that officers are not looking to identify anyone else in connection with the investigation.

He added they are working with international partners.

There is no formal extradition treaty between the UK and Pakistan.

Mr Chapman said no arrests have been made.

The girl’s mother was informed and is being supported by specialist officers, he added.

A police presence remains at the property in the quiet Woking village of Horsell and it is expected officers will be there for “some weeks”.

Locals spoke of their shock and fear the day after the 10-year-old’s body was discovered.

Many of the flowers left on the pavement outside the house had heartfelt messages written by local families attached, while one person left a stuffed unicorn.

One note read: “Sweet girl, I’m so sorry that your sparkle was put out too soon.”
