A five-year-old girl has died in a "tragic accident" at a vintage steam fair after being hit by a slow-moving vehicle.
Frantic efforts to resuscitate the girl at the showground in Cornwall where the accident happened were unsuccessful.
The girl was hit and fatally injured at 11.40am on a Saturday at the Lanlivery Steam Fair near Lostwithiel.
Foster parents of the un-named child gave their permission for the well-established annual two-day event to continue on Sunday.
They also attended a church service held at the field this morning in remembrance of the child.
"The child was treated by paramedics at the scene within a minute of the incident occurring as they were present at the show on a display stand within 100m of the location," the police spokesman added.
"The child was flown to Derriford hospital, where she later died.
"CPR was being undertaken at the point the air ambulance lifted from the scene. Local police attended, later being joined by officers from the Bodmin serious collisions investigation unit, who will conduct a full investigation into the incident.
"The child was with her foster parents who live in Devon, her details are not being released at this time until interested parties are all aware."
He added: "The Health and Safety Executive were informed but did not attend the scene.
"The show is due to last for two days including September 9, with the family's agreement the show will continue as planned.
"Police based at Bodmin serious collisions investigation unit are appealing for witnesses to this incident to contact them on 101 quoting log number 396 of 08/09/2012."
Diane Williams, the event secretary, said: "It was a tragic accident , a tragic accident. It is the family's wish that the rally continue today. Our hearts go out to them.
"We had a church service this morning at the field which the (foster) parents attended."
