A man has been bailed and a woman released without charge following a crash during a police pursuit on the A1 that left seven officers injured.
Five police vehicles and a BMW car were involved in the crash near Denton Burn, Newcastle, just before 02:30 BST on Wednesday, Northumbria Police said.
The man in his 20s, arrested on suspicion of causing serious serious injury by dangerous driving, has been released on police bail. The woman, who was held on suspicion of aiding and abetting dangerous driving, will face no further action.
The A1 was closed in both directions across the River Tyne, between Swalwell in Gateshead and Denton, for almost 13 hours following the crash.
Northumbria Police said officers attempted to stop the BMW in the Whickham area of Gateshead at about 02:00 over “concerns about the manner it was being driven”.
It was later seen in the Swalwell area and a pursuit was “authorised”, with the crash happening about two miles north on the other side of the river.
One Denton resident described the scene as “absolute carnage”.
The injured officers were taken to hospital with non-life threatening injuries, while the two occupants of the BMW were unhurt, police said.
