Masked students occupied the University of Sheffield’s Arts Tower to show support for Tuesday’s one-day strike by lecturers.
The group, calling themselves, Sheffield Strikes Back, took over one of the main lecture theatres, forcing its closure for the day.
The university said it supported freedom of speech within the law. “However, the university does not condone occupation of a building which has caused disruption for other students.”
