Five-year-old girl killed in Lanlivery Steam Fair crash

A five-year-old girl has died after being hit by a slow-moving vehicle at a steam fair in Cornwall.

The incident happened at about 11:40 BST on Saturday at Lanlivery Steam Fair near Lostwithiel, police said.

The girl was treated by paramedics before being flown to Derriford Hospital where she later died.

Devon and Cornwall Police said the girl, who has not been named, had been at the event with her foster parents, who were from Devon.

An investigation is being carried out and the Health and Safety Executive has been informed.

The family from Honiton, who had been running a stall at the event, agreed to the event continuing on Sunday as it was raising funds for the Cornwall Air Ambulance and Fleet, a charity which supplies emergency equipment.

Diane Williams, secretary of the show, said: "They told me categorically that they really wanted the rally to continue.

"They said the people that helped her were Fleet and the air ambulance and they wanted the rally to continue to support those charities."

Anyone who witnessed the incident is urged to contact police.
