Three people including a 16-year-old boy have died after a car caught fire following a crash in Cornwall.

A group of teenagers have been arrested on suspicion of causing death by dangerous driving, Devon and Cornwall Police said.

Officers rushed to the A390 near St Ive, Liskeard, shortly before midnight on Tuesday after a car was reported to have left the road and caught fire.

The boy and two men aged 18 and 30 were found inside and declared dead at the scene.

Two girls and two boys from Liskeard were later arrested and remain in custody, the force said.

Officers also seized a vehicle believed to have been involved in the “tragic incident”.

Sergeant Tina Green, of Devon and Cornwall Police, said: “Our thoughts are with the families and friends of those who lost their lives and our investigation remains ongoing to understand the full circumstances of how this tragic incident occurred.

“Whilst our inquiries are ongoing there will be an increased police presence in the area of the collision and in the wider Liskeard area.

“I would encourage anyone with information which might assist police and anyone who was travelling in the area and may have relevant dashcam footage to report it to us.”
