The father of 10-year-old Sara Sharif is being sought by detectives investigating her murder in Woking last week, along with his partner and his brother, Surrey Police said.
Sara was found at her home after officers were called from Pakistan by her father, Urfan Sharif, at around 2.50am on August 10, Surrey Police said.
The discovery at the semi-detached property in Hammond Road sparked a murder probe.
Detective superintendent Mark Chapman, from the Surrey Police and Sussex Police major crime team, said Mr Sharif, his partner, Beinash Batool, and his brother, Faisal Malik, are suspects in the investigation.
He said it is believed Mr Sharif travelled to Islamabad on August 9, a day before Sara’s death was discovered, with his partner Ms Batool, and his brother Mr Malik.
They travelled with five children aged between one and 13-years old, he added.
There is no formal extradition treaty between the UK and Pakistan, but Mr Chapman said that people have been extradited from the Asian country before.
Police are working with the Crown Prosecution Service, Interpol, the National Crime Agency and 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, Mr Chapman said.
Sara’s mother is being supported by specialist officers and police say the two have not been in contact.
Olga Sharif described her daughter as “an amazing child” in an interview with The Sun and told the newspaper that her life “will never be the same again”.
