M1 Leicestershire crash: Man killed in eight-vehicle pile-up
One man has died and three people have been injured in a crash on the M1 involving a lorry and seven cars.
The motorway was closed after the collision on Tuesday evening, between junctions 21A and 22 in Leicestershire. It reopened on Wednesday afternoon.
A man, 48, from London, died in the crash. Two people have been discharged from hospital but a woman remains there in a serious but stable condition.
A 36-year-old woman who was arrested has been released on bail.
Parts of the motorway had to be resurfaced, due to the seriousness of the collision and a diesel spillage, police added.
Bill Livingstone, who was driving past the scene after the crash, said: "It was probably one of the worst I have seen for a long time.
"A lorry had jack-knifed and gone into the central reservation, there were cars lodged underneath it and and some cars were on their roofs.
"I feel sad for everyone involved."
Leicestershire Police initially said the crash had involved a lorry and six cars.
Insp Jason Ross, head of roads policing, said: "Teams have been working throughout the night on what is a very complex situation as a result of a collision involving eight vehicles.
"The road closures have caused significant disruption and I want to thank motorists for their continued patience."
Insp Ross appealed for anyone who may have seen the crash to come forward.
