No-one in the Birmingham bomb plotters' own community tipped the police off with their concerns, despite finding out they were sending young men to terror training camps in Pakistan.
Three Birmingham men were found guilty of planning a massive terrorist bomb attack, while a further six had previously admitted their involvement in the plans.
But at no point during the 18-month investigation by the West Midlands counter-terrorism unit did anyone in Birmingham's Muslim community inform on the behaviour of Irfan Naseer, Irfan Khalid and Ashik Ali, raising questions over the health of relations between officers and community leaders.
