Two people have been arrested on suspicion of the murder of a one-year-old adopted baby boy.
The tot was living with his adoptive parents in Barrow when he died in January.
He was still under the care of Cumbria County Council and the local authority have now referred themselves for an independent review.
Police received a report from North West Ambulance Service on January 6 this year after being called to an address in Barrow, LancsLive reports.
The baby was initially taken to Furness General Hospital and then transferred to Alder Hey Children’s Hospital for specialist medical care due to his critical condition.
He passed away the next afternoon on January 7.
A 37-year-old woman and a 34-year-old man, both from Barrow have been arrested on suspicion of murder.
They were also held for causing and allowing the death of a child and two other counts of assault/ill treatment/neglect/abandon a child/young person to cause unnecessary injury.
Both have been released on bail as the investigation continue.
John Readman, executive director of People at Cumbria County Council, said in a statement: “This is a deeply distressing case and our thoughts are with the little boy’s family.
“We can confirm that he was looked after by the Local Authority and at the time of his death was placed with adoptive parents.
“The county council, as part of the Cumbria Safeguarding Children Partnership, has recommended that a full independent safeguarding review is carried out.
“A police investigation is also ongoing, and so we are unable to make any further comment at this stage.”
