The Prevent Duty requires universities in the United Kingdom to identify and report students who might be seen as ‘vulnerable’ to radicalisation. Since its introduction in 2015, the duty has been subject to increasing empirical research in the education sector. However, there has been limited research that specifically explores Muslim students’ perceptions of Prevent in British universities. This paper directly addresses this gap in research by drawing upon the qualitative experiences of 25 university students who self-identified as ‘British Muslims’. Individual, semi-structured interviews were transcribed and analysed using Thematic Analysis. The findings demonstrate the securitisation of higher education and ‘policing’ of Muslim students. The paper draws on Pantazis and Pemberton’s use of the ‘new suspect community’ thesis in order to examine participants’ views and experiences. When analysing the data, three particular themes are especially prominent: as a tool of ‘surveillance’, Prevent hampers freedom of speech, threatens student activism and forces Muslim students to hide their Muslim identity to avoid being labelled as ‘radical’ or ‘vulnerable’ to terrorism. It will be concluded that the ‘surveillance’ function of Prevent is problematic on the grounds that it renders universities ‘modern-day panopticons’.
