Most individuals arrested under Britain's terrorism laws since September 11 have been released without charges, with only 13 per cent of those detained convicted of terror offences, latest official statistics show.
Figures released on Wednesday also show that British Asians are at least twice as likely to be arrested by terror police than members of other ethnic groups, a trend that has also fueled resentment in the Muslim community.
Only 13 per cent of those arrested post 9-11 were convicted of terror offences, statistics have shown, sparking criticism from human rights organisations.
Shami Chakrabarti, director of human rights group Liberty, said it was "worrying" that "the overwhelming majority" of those arrested were not guilty of any charge and that half were not charged at all.
Figures show that 56 per cent of 1,471 terror suspects detained between September 2001 and April 2008 were not charged. Of those arrested, 102 were convicted of terror offences and 94 were convicted on terror-related charges.
Home Office minister Vernon Coaker said the 196 convictions highlighted the "real and serious threat from terrorism" faced by the UK.
