A new survey of Muslim students in Britain shows 10 percent would not inform police if they knew of a fellow Muslim planning a terrorist attack.
While 72 percent said they would inform police right away, some said they "would never grass on a Muslim," according to the poll of 466 students by the Federation of Student Islamic Societies.

Others said they would not inform because they didn't trust police, the Times of London reported.
Britain's Higher Education Minister Bill Rammell told the paper he found the findings extremely worrying.
According to the survey, 85 percent of the Muslim students condemned the terrorist attacks in London last summer.
The Times said the survey coincided with the suspension by Middlesex University of Keith Shilson, president of the student union, for refusing to cancel a public meeting with the controversial Muslim group Hizb ut-Tahrir.
