Tributes have been paid to a detective constable who died in a house fire along with her two young sons.
The bodies of Heather Bickley (46), six-year-old Oscar, and Felix (10) were recovered from their home in Anglesey following the blaze early on Tuesday.
North Wales Police, for which Mrs Bickley worked, was investigating the cause with the fire service.
Officers are keeping an open mind but sources said the blaze did not appear to be suspicious.
Mrs Bickley's husband John was not in the house at the time. Police have not confirmed reports that he arrived at the scene shortly after the fire brigade and was injured when he attempted to get inside and rescue his family.
Chief Superintendent Mark Jones said Mrs Bickley was a “trusted, respected and experienced” officer.
