Students staged a sit in at Sheffield Hallam University’s students’ union – claiming the organisation was suppressing freedom of speech.
Police were called to the Hubs building, Paternoster Row, after 30 students occupied management offices.
They were protesting against a union decision to call upon all student university societies to stop any political fundraising and activism.
The move was sparked by a group campaigning in favour of Palestinian solidarity.
Union officer Deborah Berman said all student groups supported by the union they must work towards the same aims – supporting and enhancing the student experience.
She said activism and fundraising could not be the guiding aims of any society.
Jonny Dickens, Sheffield Hallam Socialist Students member, said: “The latest incident at Hallam union is a clear attempt to depoliticise and silence its students.”
After 45 minutes, the sit-in ended with no arrests made.
