A unit of Bangladesh Chhatra League opened fire on students in Savar on Monday afternoon, killing one and injuring seven.
The attack created unrest in the area, causing students to protest and clash with the police which further injured at least 50 more students.
According to several students of City University situated in Savar, two students called Sayeed and Bappi had a row about seniority on Sunday. The two had resolved the matter between themselves there and then.
Bappi and Sayeed were set to meet again on Monday to come to another resolution when a Shaon, leader of Ashulia sadar Chhatra League unit, arrived on campus with 40-45 men on about 20 motorbikes.
The Ashulia BCL leader had come to support Bappi in the parlay, but he and his men opened fire on the students, according to several student testimonies.
