A PLAYWRIGHT handed himself in to the police on Friday after the Prime Minister suggested in his United Nations speech that people “peddling lies” about 9/11 were to blame for young Muslims leaving this country to fight for the Islamic State.

Peter Neathey said he was “deeply shocked and disturbed” by David Cameron's speech before marching into Kentish Town Police Station in Holmes Road with a DVD about the mysterious “Building 7 collapse” and a hand-written statement.

Mr Neathey, who has lived in Kentish Town for 35 years, had recently put on a play about the  World Trade Centre attacks at the Etcetera Theatre in Camden Town. Former MI5 spy David Shayler was among the performers.

Mr Neathey said: “Hundreds of people from the local community have so far come to see my play. It has been universally well received as a catalyst for intelligent thought, discussion and debate. No one has expressed concern that it might be a recruiting tool for violent extremism.”

He added: “After extensive research, I became convinced that the official 9/11 narrative was in fact the 'lie'.”

After a 20 minute discussion, police said they would not arrest Mr Neathey as he had not committed a crime. 

In his speech to the UN in September, Mr Cameron said: “As evidence emerges about the backgrounds of those convicted of terrorist offences it is clear that many of them were initially influenced by preachers who claimed not to encourage violence, but whose world-view can be used as a justification for it: the peddling of lies: that 9/11 was a Jewish plot and the 7/7 London attacks were staged; the idea that Muslims are persecuted all over the world as a deliberate act of Western policy; the concept of an inevitable clash of civilisations.”
