The incident happened during a protest against the Church of Scientology on May 10. Demonstrators from the anti-Scientology group, Anonymous, who were outside the church’s £23m headquarters near St Paul’s cathedral, were banned by police from describing Scientology as a cult by police because it was “abusive and insulting”.

Writing on an anti-Scientology website, the teenager facing court said: “I brought a sign to the May 10th protest that said: ‘Scientology is not a religion, it is a dangerous cult.’

”’Within five minutes of arriving I was told by a member of the police that I was not allowed to use that word, and that the final decision would be made by the inspector.”

A policewoman later read him section five of the Public Order Act and “strongly advised” him to remove the sign. The section prohibits signs which have representations or words which are threatening, abusive or insulting.

The teenager refused to back down, quoting a 1984 high court ruling from Mr Justice Latey, in which he described the Church of Scientology as a “cult” which was “corrupt, sinister and dangerous”.

Liberty director, Shami Chakrabarti, said: “This barmy prosecution makes a mockery of Britain’s free speech traditions.

“After criminalising the use of the word ‘cult’, perhaps the next step is to ban the words ‘war’ and ‘tax’ from peaceful demonstrations?”

Ian Haworth, from the Cult Information Centre which provides advice for victims of cults and their families, said: “This is an extraordinary situation. If it wasn’t so serious it would be farcical. The police’s job is to protect and serve. Who is being served and who is being protected in this situation? I find it very worrying.

“Scientology is well known to my organisation, and has been of great concern to me for 22 years. I get many calls from families with loved ones involved and ex-members who are in need of one form of help.”
