Security measures were intensified at Khajeh Nasir Toosi University of Technology in Tehran on Tuesday, with reports of tighter controls on student entry a day after students said they would join protests.
Students and local sources reported increased checks at campus entrances, with security personnel monitoring access and movement inside the university.
The measures followed a statement issued by students on Monday announcing their intention to take part in protests linked to economic conditions.
Universities in Tehran have played a visible role in recent protest movements, and campuses have often faced heightened security when demonstrations are expected.
