Two ponies were killed after straying on to the A1 near Grantham, while corralled in a field at Arena UK for a mounted games competition.
Lincolnshire police say the ponies, belonging to a family from South Wales, were killed outright in collisions with a Mercedes car and an articulated lorry. Neither driver was seriously injured.
A farrier was sent by Arena UK to identify the dead ponies — a grey and a dark bay, said the police spokesman. She said officers will be investigating how the ponies managed to escape.
The Norman Patrick Memorial Inter- Counties Championships were held at Arena UK between 25 -27 August.
Mary Worth, executive officer of the Mounted Games Association of Great Britain, said: “There was an accident on Monday while we were holding our inter-counties championships.
“At about 4am it was discovered that two ponies had escaped and they had got on to the A1.”
Lauren Humphries, owner of Arena UK, said: “We are devastated and terribly sorry for this family.
“Ponies were corralled at the owners’ own risk and these ponies were within electric fencing around their lorry.”
The Mounted Games Association holds games events for children, older teenagers and adults.
