A three-week-old boy who was stabbed along with his mother last week has died in hospital.

The child was taken to hospital with his 21-year-old mother after they were found with life-threatening injuries at their home in Wallsend in Newcastle last Wednesday.

The boy was in a critical condition and received round-the-clock care before he was pronounced dead on Sunday, Northumbria police said. His mother is in a stable condition.

A 27-year-old man who police said was known to the victims was charged with two counts of attempted murder last week.

Denis Erdinch Beytula, of Wallsend, appeared before North Tyneside magistrates court on Thursday where he was remanded in custody. He is due to appear at Newcastle crown court on 31 October.

DCI Dave Cole, of Northumbria police, said: “This is a devastating time for the baby’s family. Specialist officers continue to offer them support and I know the community in Wallsend are by their side too. It is impossible to imagine what they are going through and I would ask the public to continue to respect the family’s privacy at this time.”

A court order remains in place banning the naming of the baby, and police asked members of the public to respect that order.
