More than 50 students remained in police hands on Thursday following their arrest on Wednesday for taking part in lunchtime protests called by the Save Zimbabwe Campaign, an opposition coalition of civil society organizations.
Campaign spokesman Pius Wakatama said no other arrests were reported around the country in the so-called "sound of freedom" protests which involved five minutes of noise to signal popular discontentment with government policies.
Wakatama said the students took the protest a step further by marching through the streets and university campuses. Police arrested a dozen or more at the National University of Science and Technology in Bulawayo.
Zimbabwe National Students Union President Promise Mkhwananzi told reporter Jonga Kandemiiri of VOA's Studio 7 for Zimbabwe that some of the arrested students were in the midst of year-end examinations and stood to lose academic ground.
