A 12-day-old baby has been mauled to death by a dog.

The youngster was rushed to hospital on Sunday afternoon but died shortly afterwards in Doncaster, South Yorkshire.

The mum of the tragic tot has now suffered a double tragedy after she lost her long-term partner and the father to her three other children to sepsis around 18 months ago, according to a neighbour.

Police officers had been called to a residential property in Welfare Road amid reports a dog had attacked the young boy.

South Yorkshire Police confirmed a 35-year-old man and a 27-year-old woman have been arrested on suspicion of gross negligence manslaughter.

Both have been bailed pending further enquiries, police continued.

Residents of the quiet street said they were shocked to hear of the tragic incident.

One, who did not wish to be named, said: "It is heartbreaking, it's just shocking.

"It's a tragedy upon a tragedy.

"They just looked like such a lovely family, they were always together and always happy."

Neighbours said they did not know what breed the dog was, but said it was "big and furry".

They said the older children – two boys and the youngest, a girl – were "lovely and polite" and "well cared for".

Floral tributes were left outside the house following the tragedy.

A police liaison officer at a neighbouring property advised that the family is too upset to speak.

Police cars flooded the road on Sunday and forensic officers searched the scene after the dog was taken away from the property in a van.
