A mother and her six-year-old daughter who died after a car driving the wrong way up the A1 crashed head-on into their vehicle have been named by police.
Joanne Richardson, 40, and her daughter Mya were passengers in a black Jaguar hit by a burgundy-coloured Jaguar which was heading the wrong way up the southbound dual carriageway near Newcastle on Sunday night, police said.
A six-month-old baby and the children's 37-year-old father, who was driving the black Jaguar, suffered minor injuries and were treated at Newcastle General Hospital.
It was the same hospital where Mya was taken in a critical condition following the smash half a mile north of the Gosforth park interchange at around 9.30pm on Sunday.
She died on Monday afternoon, while her mother was pronounced dead at the scene.
The driver of the other car was taken to the Queen Elizabeth Hospital, Gateshead, with minor injuries.
Mrs Richardson, who came from Billingham, Teesside, was a front seat passenger in the car, while the children were in the back.
The 61-year-old, from Blyth, Northumberland, was initially held on suspicion of dangerous driving but was re-arrested on suspicion of causing death by dangerous driving when Mrs Richardson's death was confirmed.
Officers were still trying to establish the course of events leading up to the collision.
