A 64-year-old grandmother has died after being savaged by a dog in Cardiff.
Rhona Greve, was attacked by the animal at her home in Ely. Officers were called to the property shortly after 10pm, after receiving reports that a woman had suffered serious injuries as a result of a dog attack.
Despite attempts by police officers and paramedics to save her, the woman later died at the University Hospital of Wales.
Neighbours said there had been a dog at the house for years and children were often seen playing in the garden with the pet.
Mrs Greve's husband had died a few years ago.
Superintendent Andy Valentine of South Wales Police's Eastern division said: "This is tragic incident, which I know will shock and upset the local community. The woman's family are understandably extremely distressed and are being supported by specially trained police officers.
"I would like to reassure local residents that this is an isolated incident and a thorough police investigation into what happened on Friday is being conducted. I would also like to thank the local community for their support and co-operation during the investigation so far."
Ely councillor Susan Goddard said: "This is a terrible tragedy, it's just too awful to comprehend. It's terrible."
Two men have been arrested and a 23-year-old man has been charged with two offences under the Dangerous Dogs Act in connection with the incident. A 17-year-old male, who was also arrested, is on police bail pending further enquiries.
The 23-year-old man will appear at Cardiff Magistrates Court tomorrow.
Flowers and tributes have been laid at the house, which has now been taped off by police.
