David Cameron has promised to personally look into the circumstances surrounding the murder of 14-year-old schoolgirl Alice Gross, whose body was found on Tuesday in west London.
Speaking to reporters in Kabul after a visit to Afghanistan, Mr Cameron said "I will look at all the circumstances of the case: what lessons there are to learn, whether that is about exchanging information or whether that's about the importance of keeping our country safe."
"I am going to look at that and I will come back to you," he added.
The Prime Minister described the death of Alice, who went missing on August 28, as a "horrific case", saying: "Anyone with a daughter will have just felt sickened by what has happened and what that poor family has had to go through."
Police previously searched the area where the decomposed body, thought to be that of Alice Gross murder suspect Arnis Zalkalns, was found.
