"On the night of Wednesday June 30th members of the Animal Liberation Front mounted a daring raid on the RMC site at their international HQ at Thorpe in Surrey.

Powerful incendiary devices were left on site and resulted in the destruction of three lorries, the site office and severe damage to associated industrial buildings and machinery.

According to media reports eight fire appliances attended the site and 50 firefighters took three hours to put the fires out.

This attack is a warning to RMC that collaboration in animal torture at Oxford or anywhere else will not be tolerated, and a further warning to all involved in building the Oxford laboratory to expect similar ruthless treatment.

You have been warned."
