Some journalists believed that the White Wolves are a C18 splinter group, alleging that the group had been set up by Del O'Connor, the former second-in-command of C18 and a member of Skrewdriver Security.[17] The document issued by the White Wolves announcing their formation has been attributed to David Myatt,[18] whose Practical Guide to Aryan Revolution allegedly inspired the nailbomber David Copeland,[19][20] who was jailed for life in 2000 after being found guilty of causing a series of bombings in April 1999 that killed three people and injured many others.
