The bereft relatives of a newborn baby who died after being mauled by his parents' two Staffordshire Bull Terriers are supporting the couple 'all the way', it was revealed today.

Reuben McNulty was just one month old when he was attacked at home in Peterborough at 1.47am on Sunday November 18 but has died four weeks later.

Cambridgeshire Police today announced the newborn perished as a result of his injuries inflicted by the dogs, Fizzy and Dotty.

The Staffordshire Bull Terriers, owned by his parents Dan McNulty and Amy Litchfield, have since been put down, and the couple were later arrested on suspicion of child neglect and released on bail.

Dan‘s sister Stacey McNulty was among relatives holding a vigil at her nephew's bedside at Addenbrooke's Hospital, Cambridge, where he died yesterday morning.

Today she told Facebook friends she was 'feeling heartbroken' hours after posting: 'By your side all the way Dan McNulty and Amy Litchfield. So proud of my little angel of a nephew. We love you so much'.

Detectives said today the baby's death is not being treated as suspicious but confirmed the couple arrested are still under investigation.

Today the flat where Reuben was attacked was being emptied by friends and family - but the little boy's parents were unavailable for comment.

Reuben's parents Amy Litchfield and Dan McNulty are believed to have been arrested on suspicion of child neglect and released on bail

Police said in a statement released today: 'Both of the dogs have been destroyed.

'A 28-year-old woman and a 31-year-old man, both from Yaxley, who were arrested on suspicion of child neglect, have been released under investigation.

'The death is not being treated as suspicious and has been handed to the coroner.'

The incident happened in a cul-de-sac in the village of Yaxley, near Peterborough in Cambridgeshire.

The youngster was born four weeks premature early earlier in November. He is pictured with his mother

Miss Litchfield's father, Peter insisted at the time it was a 'freak accident'.

He said: 'Everyone's making a big thing of it. They've done nothing wrong and the way it's being portrayed at the minute they're horrible parents.

'The bloody aren't. They've been fantastic. If they were horrible parents they wouldn't be sitting with that young lad now.'

But angry locals said they had warned about the risks of allowing the dogs - Fizzy and Dotty - near a newborn and described the pets as 'vicious'.

One neighbour, who lives opposite the flat, said: 'He (Dan) was showing people his new baby because he was so proud of it.

'When he showed me the pictures I said 'Be careful, because those dogs might not be used to the baby'.

'I know what dogs are like when they get jealous. He said 'I will do. Me and Amy were thinking about that anyway'.'

Another neighbour added: 'I have seen those dogs before and they are vicious and will show their teeth at anyone'.

Reuben, who was born around a month premature, fought his injuries for a month but would succumb to them yesterday

The couple had been celebrating the birth of their son, before the horrific attack

The boy's grandfather said the dogs have 'never been dangerous, they've been docile dogs' - but neighbours said they were 'vicious'

The incident unfolded at the family's home in Yaxley, Cambridgeshire, pictured, where one neighbour claimed they warned the parents about having the bogs around the baby. They have now been destroyed

The man said he was woken by the sound of police sirens and saw the couple being led out of their home in handcuffs.

Cambridgeshire Police confirmed they were called at 1.47am on Sunday November 18.

A spokesman for the force said at the time: 'The baby was taken to Peterborough City Hospital before being transferred to Addenbrooke's Hospital in Cambridge with life-threatening injuries.

'A 28-year-old woman and a 31-year-old man, both from Yaxley, were arrested on suspicion of child neglect and have been bailed until December 15.

'Two dogs, Staffordshire Bull Terriers, were taken from the property and are in police kennels. Police remain at the scene and an investigation has been launched.'
