A 49-year-old man was arrested near Glasgow on suspicion of murder following an attack on a woman and teenage boy at a house in the village of Linton, Northumbria Police said in a statement.
At about 8.55pm on Sunday, November 15, the force received a report that a 47-year-old woman and a 15-year-old boy had been assaulted inside an address on Foxcover.
The woman, who has been named by police as Caroline Kayll, sadly died in hospital while the teenage boy suffered serious injuries but non-life threatening injuries and has since been discharged from hospital.
Those inquiries focused on Glasgow and now police have confirmed that a 49-year-old man has been arrested near to the city.
He remains in police custody at this time, Northumbria Police said on Saturday.
Superintendent Paul Milner said: “In recent days our officers have been carrying out inquiries across the region and north of the border.
“Those inquiries have now led to the arrest of [a man] on suspicion of Caroline’s murder and the serious assault of a teenage boy.
“We want to reassure the public that this was an isolated incident and at no point were they at risk.
“Inquiries into the circumstances leading up to this attack will continue but we would ask the public to avoid speculation.
“This is a live murder investigation and it is an incredibly difficult time for Caroline’s family and the teenage boy injured in the attack.
“They will continue to receive our full support while we would ask anyone who has information that could assist our investigation to get in touch.”
A 58-year-old man arrested on suspicion of assisting an offender earlier this week has since been released under investigation.
Anyone who believes they may be able to assist police is asked to report online at the Northumbria Police website quoting log 421 19/11/20.
