A woman has been arrested on suspicion of killing her eleven-month-old baby daughter.
Jade Ruck, 22, was arrested after Harley Ruck was found by police on Saturday morning at their home in Abergavenny, South Wales.
Despite frantic efforts by paramedics, she died from injuries sustained from stab wounds.
In a statement, the little girl's family branded her death an 'horrific tragedy'.
They said: 'Harley was our beautiful, happy, loving little daughter, granddaughter, great granddaughter, niece and cousin. She was loved dearly and will be sadly missed by all around her, especially by her lost, heartbroken mum.'
Detective Chief Inspector Jon Williams told reporters: 'This is an extremely distressing incident. I would reiterate that we are not looking for anyone else in connection with the death at this time and there is no risk to the wider community. I have a team of approximately 25 detectives and staff working on this case. Inquiries are continuing in the area and forensic examiners remain at the scene.'
As neighbours left floral tributes and soft toys outside the child's home, one told journalists: 'We can't believe this. The baby was so cute and such a pretty little thing. Police arrived in the street very early followed by the ambulance. Then all hell broke loose and there were cops everywhere. It's all so sad.'
A police spokeswoman said: 'Initial results from the post-mortem examination have established the child died from multiple stab wounds.'
Jade Ruck is currently being held under the Mental Health Act.
