Police continue to question a man on suspicion of murder after the deaths of three generations of a family in a fire in Cwmbran. Forensic officers are still at the scene in Coed Eva.
46-year-old Kim Buckley, her daughter Kayleigh Buckley, 17, and Kayleigh's six-month-old daughter Kimberley Buckley were found dead in their home after the fire broke out in the early hours of Tuesday morning.
The arrested man has been named locally as 27-year-old Carl Mills, who is believed to be Kayleigh Buckley's former boyfriend.
Gwent Police received a call at approximately 3.30am from fire crews, who were attending a fire at an address in Tillsland, Coed Eva, Cwmbran.
Forensic examination of the property will be carried out, with officers carrying out house-to-house enquiries as well.
Chief Inspector Steve Corcoran from Gwent Police and Area Manager Dewi Rose from South Wales Fire & Rescue Service have appealed to the public for any information that might help them in their investigation.
"I would appeal to anyone who heard or saw anyone suspicious prior to 3.30am to contact us," said Chief Inspector Corcoran.
"This was a tragic and horrendous incident. I would like to pass on my sympathies and thoughts to the family, and to the wider community."
He described how two local men 'valiantly and bravely' attempted to enter the house, but were driven back by flames.
Neighbours told ITV Wales of their shock at what had happened in the close-knit community.
"Everyone around here is really devastated," said neighbour Tania Brown.
"I heard about it at around seven o'clock this morning. I just wanted to cry."
Chief Inspector Steve Corcoran, speaking on behalf of Gwent Police, confirmed that a 27-year-old man from the Manchester area has been arrested on suspicion on murder.
Gwent Police say they have referred the case to the IPCC as officers had been called to the property in the past.
