Police investigating the French Alps shooting spree have evacuated an area around the victims' home in Surrey due to "concerns" about items found at the address.
Neighbours living close to the property in the affluent village of Claygate were prevented from returning to their houses as detectives examined the mock-Tudor house for clues.
Police said in a statement: "Surrey Police can confirm that due to concerns around items found at the address ... officers have extended the cordon surrounding the property. Neighbours in the immediate area are being temporarily evacuated."
Members of the media were also moved back around 200 yards.
Attention on the property intensified as police in Annecy in France waited to question seven-year-old Zainab al-Hilli, who has regained consciousness following the attack that left her parents dead.
Her father Saad al-Hilli, 50, was murdered in his car alongside his dentist wife, Iqbal, on Wednesday while the family holidayed in the picturesque region.
Mrs al-Hilli's mother also died in the shooting along with Sylvain Mollier, 45, a French cyclist who apparently stumbled across the attack. Zainab's younger sister Zeena, four, who survived after she hid behind her mother, flew back to Britain with carers on Sunday.
Soon after the cordon was extended, a Royal Logistic Corps bomb disposal truck arrived. Officers were seen apparently receiving a briefing at a neighbouring home.
Police plan to look at aspects of Mr al-Hilli's life to try to find a motive for the murders and also speak with his brother, Zaid Hilli. Investigators have disclosed that Mr al-Hilli's brother has approached UK police to deny any feud with his sibling over an inheritance.
Police have yet to speak to Zainab, who was shot and beaten during the ordeal and is seen as a key witness. She remains under sedation after coming out of a medically-induced coma. Public prosecutor Eric Maillaud said the child will be interviewed as soon as doctors allow it.
