The men, aged 30 and 22, were arrested on the campus of the University of Nottingham on Wednesday morning.

One of the men is believed to be a student at the university while the other is a former student.

A police spokeswoman said the men were arrested during a joint operation between Nottinghamshire Police and the Midlands Counter-terrorist Unit.

Superintendent Simon Nickless, of Nottinghamshire Police, said: "Officers are working with community representatives to offer support and reassurance. The response has been calm and rational.

"Feedback is that people accept that this is the sort of operation that is necessary and reasonable for the welfare of communities."
