AN investigation is underway today into a crash which killed a man on a Hampshire motorway.

He died after neing involved in a three car crash on the M3.

The 37-year-old man from Southampton was caught in a collision on the M3 southbound carriageway between Winchester Services and Junction Eight for Andover.

The pedestrian was struck by a car after he got out of his Mitsubishi ASX 4 after it was initially in collision with another car, police say.

The road was closed for several hours following the crash before it reopened yesterday afternoon.

Now officers are urgently appealing for anyone who saw the incident to contact them.

Emergency services were called to the scene at 6.39am following a collision between junctions Eight and Nine on the southbound carriageway close to Winchester Services.

Police say initial investigations show that his vehicle was in collision with a Skoda Superb which resulted in him getting out of his vehicle.

He was then struck by a third vehicle, a Citroen Berlingo.

He was pronounced dead at the scene.

The drivers of the two other vehicles were uninjured.

The stretch of motorway was closed for several hours for officers to conduct their investigations.

Roads Policing Sergeant Barry Long said: “We know that closing such major route for several hours causes huge inconvenience for motorists but we would like to thank all those caught up in the back log for their patience and understanding that we will always do our best to reopen roads as quickly as possible.

“We have already spoken to many motorists who witnessed what happened this morning but if there are any other witnesses who have yet to speak us, please get in touch.

“We would also like to speak to anyone who saw any of the vehicles prior to the collision.”

As previously reported a spokesman for South Central Ambulance Service (SCAS) said that the man had "walked onto the carriageway".

The spokesman said the car had contained a man and a woman and added:  “The man then got out of the car and walked onto the carriageway. He was then struck.”
