Animal rights campaigners have claimed responsibility for two petrol bombs which exploded at an Oxfordshire farm.

The incendiary devices caused thousands of pounds of damage at Field Farm in Appleton near Abingdon at about 11pm on May 6.

An anonymous posting on animal rights website Bite Back said the farm was attacked because it is involved in transporting animals to their deaths and raising animals to be killed.

David Morgan, managing director of Field Farm in Netherton Road, Appleton, near Cumnor, said after the incident that it was lucky that no-one had been hurt in the incident in which petrol incendiary devices were put underneath two large tractors to set off the fires and the fuel tanks exploded.

Mr Morgan's son Danny, who lives on the farm, spotted the fire. He believes he disturbed the intruders and saw people running away.

Eight fire crews were sent to tackle the blaze and the farm lost lost about 200 tonnes of hay bales.

Police are now appealing for information from anyone who saw the arsonists or has any information to contact them on 08458 505505 or anonymously on 0800 555 111.
