The family of a woman who was mauled to death by a group of dogs she was walking say they are going through "an extremely difficult time".
The 28-year-old woman from London, who has not yet been formally identified, died after she was set upon by the animals in Caterham, Surrey, on Thursday 12 January.
Surrey Police detained a total of eight dogs following the incident and detectives are keeping their owners up to date with the investigation. The animals are still being held.
On Tuesday, police released an update in which they said they were working with both a forensic pathologist and a veterinary pathologist as part of their investigation.
"These enquiries will take some time to complete," the force said.
Surrey Police also released a statement from relatives of the victim, who said they had been the subject of a "significant level of media interest" following the incident.
In a statement, the family said: "This is an extremely difficult time for us.
"We continue to appeal for our privacy to be respected during our time of grief."
Detective Inspector Josephine Horner, the senior investigating officer, said: "Enquiries into the circumstances surrounding this young woman's sad death continue and we will provide further updates when possible.
"We know this incident has caused real concern in the local community and neighbourhood officers have been out in the area speaking to local residents over the past few days.
"We continue to ask people not to speculate on the circumstances whilst enquiries are under way."
Surrey Police said it was believed that the woman had been walking a number of dogs at the time of the incident.
A post-mortem examination is due to be conducted by the Surrey coroner.
A second woman who received treatment for dog bites has since left hospital.
