Two police officers are among three people who have been seriously injured following a major 3-vehicle crash on Cornwall's busiest road.

Emergency services rushed to the scene of the collision on the A30 at around 8pm last night (December 7), which involved two cars and a police vehicle. A number of people suffered injuries and were treated by ambulance crews. Three men, including two police officers, suffered serious injuries and were rushed to a nearby hospital. Their families have been informed.

A stretch of the A30 was closed for 11 hours as an investigation of the scene was carried out. National Highways warned drivers of the closure and a diversion route was put in place while the road was closed.

"Once this is received we will assess it to decide if any further action is required from us."
