Police have detained 20 Chhatra League leaders and activists of Chittagong University (CU) unit after an internal clash on the campus.
Police raided two halls - Shah Amanat and Suhrawardy- after the clash and detained 12 activists of Choose Friends with Care (CFC) and eight activists of Bijoy Group on Wednesday night.
