Hunt for Britons linked to Norway killer Anders Behring Breivik
He signed the document “Andrew Berwick”, an Anglicised version of his name, and described his “mentor” as an Englishman he identified as Richard.
Scotland Yard counter-terrorism officers are now trying to establish whether Breivik visited London in recent years and whether he was part of a wider network preparing to carry out similar attacks.
The 32 year-old boasted that he was just one of up to 80 “solo martyr cells” recruited throughout Western Europe who were ready to follow his example of trying to overthrow governments tolerant of Islam.
He said he regarded himself as a successor to the medieval Knights Templar, and claimed to have been recruited at a meeting in London in April 2002, which was hosted by two English extremists and attended by eight people in total.
