A 16-year-old boy has been arrested on suspicion of murder after a 15-year-old girl died in a stabbing in Northumberland.

Police said they were called to the Priestpopple area of Hexham shortly after 5.10pm on Friday to reports that two teenagers were injured.

The boy was initially arrested on suspicion of assault, and then later on suspicion of murder. He remains in custody.

Northumbria Police said they believe the pair are known to each other and are urging anyone with information to get in touch.

Officers are carrying out inquiries in the town centre and a cordon was expected to remain in place into the weekend.
