The father of a 10-year-old girl who was found dead in a village in Surrey is being sought by investigating police and is believed to be in Pakistan.
The body of Sara Sharif was found at her home in Horsell near Woking after officers were phoned from Pakistan by her father, Urfan Sharif, at about 2.50am on 10 August, Surrey police said.
Sharif, 41, his partner, Beinash Batool, 29, and his brother, Faisal Malik, 28, are suspects in the investigation and are all understood to have travelled to Pakistan, the force said.
Det Supt Mark Chapman said it is believed Sharif travelled to Islamabad with his partner and his brother on 9 August, a day before Sara’s death was discovered.
They travelled with five children aged between one and 13 years, he added.
Chapman, from the Surrey police and Sussex police major crime team, said: “While the postmortem has not provided us with an established cause of death at this time, the fact that we now know that Sara had suffered multiple and extensive injuries over a sustained and extended period has significantly changed the nature of our investigation, and we have widened the timescale of the focus of our inquiry.
“As a result, we are trying to piece together a picture of Sara’s lifestyle but we cannot do this without the public’s help.
“That is why we are appealing for anyone who knew Sara, had any form of contact with her, or has any other information about her, no matter how insignificant it might seem, to come forward as soon as possible.”
He added: “On behalf of Surrey police, I would like to express my heartfelt condolences following Sara’s tragic death.
“Our thoughts are with her mother at this difficult time. We also fully appreciate the impact this devastating incident will have had within the local community.”
Chapman added there is no formal extradition treaty between the UK and Pakistan but people have been extradited from the South Asian country before.
Police are working with the Crown Prosecution Service, Interpol, the National Crime Agency and the Foreign Office to carry out their investigation and to liaise with Pakistani authorities.
Officers are not looking to identify anyone else in connection with the investigation, the force said.
