A MAN from Andover has been arrested on suspicion of driving under the influence of drugs following a crash on the A34 last night (Sunday).

Police were called at 6.55pm after reports of a two-vehicle collision on the northbound carriageway of the A34, between Winchester and Bullington Cross.

One of vehicles was said to have left the carriageway and "gone down an embankment", according to the ambulance service.

One person was taken to hospital with serious but not life-threatening injuries.

A 22-year-old man from Andover remains in custody after being detained on suspicion of multiple charges.

He was arrested on suspicion of driving a motor vehicle with a proportion of a specified controlled drug above the specified limit, causing serious injury by dangerous driving, driving a vehicle whilst unfit through drugs.

The fire and ambulance service were also in attendance.

Hampshire Fire and Rescue Service was called to the incident at 7.10pm, with crews from Winchester and Redbridge, Southampton, attending.

They extricated one female casualty from a vehicle with the stop call coming in at 8.20pm.

She was then taken to the major trauma centre of Southampton General Hospital with serious but not life-threatening injuries.

Another person from the same vehicle was treated at the scene for minor injuries.

South Central Ambulance Service says it sent one ambulance, a paramedic team leader in a rapid response vehicle, its full Hazardous Area Response Team and the Hampshire and Isle of Wight critical care car to the scene.

The incident was one of two to occur the A34 last night, after a second crash on the southbound carriageway was reported shortly after.

Witnesses took to Twitter to describe a scene of “utter chaos” with bumper-to-bumper traffic on both sides of the A34. Others reported being stuck in traffic for up to 45 minutes.

The northbound carriageway was closed completely until midnight, while a lane on the southbound carriageway remained blocked from around 9pm until just before 11pm, according to Highways England.
