Biological Weapons Identification Group

Home Secretary David Blunkett and Health Secretary John Reid issue a joint statement claiming “traces of ricin” and castor beans capable of making “one lethal dose” were found in a raid on a flat in Wood Green, north London, which also resulted in several arrests (see January 5, 2003). The joint statement says “ricin is a toxic material which if ingested or inhaled can be fatal… our primary concern is the safety of the public.” Prime Minister Tony Blair says the discovery highlights the perils of weapons of mass destruction, adding: “The arrests which were made show this danger is present and real and with us now. Its potential is huge.” Dr. Pat Troop, the government’s deputy chief medical officer, issues a statement with police confirming that materials seized “tested positive for the presence of ricin poison.” A small number of easily obtainable castor beans are found. But the same day, chemical weapons experts at the Defense Science and Technology Laboratory at Porton Down in Wiltshire discover in more accurate tests that the initial positive result for ricin was false: there was no ricin in the flat. But this finding will not be released publicly for two years. [Independent, 4/17/2005] Dr. Martin Pearce, head of the Biological Weapons Identification Group, confirms that there was no ricin in the flat. This report is also suppressed. [Guardian, 4/15/2004] The Ministry of Defence later confirms that the results of the Porton Down test are not released to police and ministers until March 20, 2003, one day after war in Iraq begins. [BBC, 9/15/2005] It appears that there was the intention to create ricin, based on evidence discovered in other raids, but not the technical know-how to actually do so (see January 20, 2003 and January 5, 2003).
