Kieran Horn's family cautioned over quad bike death
The father and grandfather of a boy killed in a quad bike accident have been cautioned over his death.
Kieran Horn had been helping on his family's farm at Lamerton, Devon, in March last year when his bike crashed.
Earlier this year an inquest ruled the 11-year-old's death was accidental. It is illegal for children under 13 to ride quad bikes on farms.
The Health and Safety Executive said it had cautioned Charles and Stephen Horn, but they would not be prosecuted.
In a statement, the HSE said: "Stephen Horn and Charles Horn have both been cautioned following the accident and no further action will be taken."
Kieran had volunteered to help on the farm after coming home from school and was on his way to move an electric fence when the quad bike crashed in a rutted field.
The keen horse rider - who was not wearing a helmet - was found lying beside the overturned bike by his father Charles, but attempts by paramedics to resuscitate him failed.
HSE inspector Georgina Speake told the inquest in Exeter most children under 16 were "simply not big enough in weight and height" to keep the machines stable.
