A man walking along a busy motorway has died after reportedly being hit by a car and thrown onto the opposite lane – before being struck by three more vehicles.
A teenager has been arrested after the horror crash which happened at around 2am on the motorway between junctions 1 and 2 in Bury.
Officers discovered a man who had suffered fatal injuries and four damaged vehicles.
It is thought the man had been walking along the motorway before being struck by a white Audi A5 travelling northbound.
The man is thought to have been thrown onto the southbound carriageway before being hit by three more cars, reports the Manchester Evening News .
He was declared dead at the scene. The man has now been identified, but his name and age have not yet been released.
A man, aged 19, has been arrested on suspicion of driving under the influence and remains in police custody for questioning.
Sergeant Helen Hallworth, of the Serious Collision Investigation Unit, said: “We believe we have identified this man and we have now spoken to his next of kin.
“However, we still need witnesses who may have seen this man walking up the motorway to contact us as a matter of urgency.
“As ever, any dashcam footage would be gratefully received, but at this stage any information from eye witnesses would greatly help us with our investigation into this man’s tragic death.”
The M66 was closed in both directions through Bury after the incident.
Investigation was carried out on the stretch between J1 for Ramsbottom and J2 for Bury on Saturday morning.
Diversions were put in place following the incident, leading to long delays.
The northbound stretch was due to be reopened at around 12.30pm, with the southbound stretch still closed.
