Overthrown Anarchist Faction has not claimed responsibility for an attack since March of 2000, and has presumably ceased to exist.

Animal Liberation Front (ALF) -- Umbrella Organization
Stop Huntingdon Animal Cruelty (SHAC) -- Ally

The Oxford Arson Group (or Squad) first emerged in 2005, claiming responsibility for a firebombing of a university house at Corpus Christi College, the University of Oxford.   The attack caused minor damage and no one was hurt.<P>The bombing was to protest the University's building of a new biomedical research facility, where animal testing was to occur.  The Oxford Arson Group claimed responsibility for the bombing on the Animal Liberation Front (ALF)'s website, Backbite.  The message, addressed to Oxford University read: "You cannot build the South Parks Lab without incurring massive losses." It went on: "If we have to destroy every bit of property you own we will, in order to stop you inflicting your profit driven cruelties on defenceless creatures." <P>Although little is known about the Oxford Arson Group, this incident followed a similar pattern compared with other attacks perpetrated by animal-rights extremists.  Typically groups of this nature intend to inflict property damage but not grievous injury to individuals.  This attack was notable in that a large number of incendiary devices were employed, hinting that the group meant to cause a large amount of damage. <P>The group's claim of responsibility on an ALF-affiliated website suggests that the group may be one of many small autonomous groups of people belonging to ALF and carrying out acts in its name.  Alternatively, the group is at the very least supportive of ALF's philosophy and goals which promotes "animal liberation" by "direct action."

Although Oxford Arson Group has not been directly tied to further attacks, similar incidents have targeted Oxford, and it is quite possible that the perpetrators were members or supporters of ALF and the Oxford Arson group. <P>In July 2005 ALF claimed responsibility for an arson attack on an Oxford University boathouse which caused an estimated &#163;500,000 worth of damage.  The arsonists broke into the building and covered boats and property with about 2.5 gallons of petrol.<P>In February 2007, another attempted bombing occurred at Oxford's Templeton College.  Two incendiary devices were found under a temporary building, an anonymous posting on the ALF website claimed responsibility.  "On the night of Sunday, February 18, the ALF carried out an arson attack on a temporary building of Templeton College at Kennington on the outskirts of Oxford. This latest action is part of an ongoing fight against the University of Oxford and its continued reign of terror over the unseen victims inside its animal labs."<P>Despite these bombings, construction continues on the South Parks Lab and is expected to be completed in spring 2007.  Authorities have yet to apprehend any of the persons responsible for these attacks, and as such, it is possible that extremist groups will continue to target Oxford University whether anonymously, under the ALF moniker, or as the Oxford Arson Group.
