A number of groups have already infiltrated university campuses where young, intelligent, middle class students are recruited. It is a growing problem that people don't know about until it affects their family. Its official website claims the group has grown by almost 200,000 since 1987. Ayman Ashar was a student in London when he was recruited by the London Church of Christ. Today he runs the support group Triumph Over London Cults.
Music festivals are also good recruiting grounds.
The group has since been banned from next month's Reading Festival.
