M5 carriageway reopens after crash in Devon
The M5 northbound carriageway has reopened after an eight vehicle pile-up which left a 21-year-old woman critically injured.
The woman was among seven people injured in the crash at Cullompton, near Exeter, between junctions 29 and 28 on Thursday.
Cars and debris were strewn along the carriageway for 300m (984ft).
Vehicles had been diverted at Exeter from the carriageway after the crash at 2100 BST.
A police helicopter and a search and rescue helicopter from RMB Chivenor helped airlift injured passengers after the crash.
A one-year-old girl was taken to hospital as a precaution.
Sgt Aaron Bevan, of Devon and Cornwall Police, said: "It was quite a major incident.
"At that time of night the M5 was very busy."
He appealed for the driver of a blue lorry who witnessed the crash to get in touch with police.
Firefighters using power-cutters and thermal imaging cameras released five people trapped in their vehicles.
Casualties were taken to Derriford Hospital in Plymouth, where the critically injured woman is being treated, the Royal Devon and Exeter Hospital and Musgrove Park Hospital in Somerset.
A number of less seriously injured people are believed to have been treated at the scene.
