Three generations of the same family who all died in a suspected arson attack have been named by police.

Grandmother Kim Buckley, 46, her daughter Kayleigh Buckley, 17, and her six-month-old grand-daughter Kimberley Buckley all died.

Fire ripped through their home in Tillsland, Coed Eva, Cwmbran, south Wales, in the early hours of Tuesday.

Gwent Police have arrested a 27-year-old man from the Manchester area on suspicion of murder.

Police and firefighters were called to the address in Cwmbran at about 3.30am, a police spokesman said.

"Three people were confirmed deceased inside the address, two adults and one infant believed to be 46-year-old Kim Buckley, her daughter 17-year-old Kayleigh Buckley and her granddaughter six-month-old Kimberley Buckley although they have yet to be formally identified," he said. "The family have asked to be left alone to grieve at this time."

Police and fire service forensic investigations of the scene of the tragedy are under way. House-to-house inquiries in the area and searches of the surrounding areas have also begun.

Shocked neighbours described grandmother Kim Buckley as a "bubbly, popular character who was liked by all who knew her."

Friend Terena Mellor, 26, said: "She was a character, very loud and fun-loving. If she saw you on the other side of the road she would have shouted out your name and ask you how you were."

She said that she believed that daughter Kayleigh had been pregnant with twin daughters but had tragically lost one in birth. The surviving daughter, Kimberley, was only recently allowed home after spending time in intensive care at the Royal Gwent Hospital, in Newport.
