Bangladesh Chhatra League men yesterday attacked dozens of Dhaka University students who were demonstrating in front of the vice-chancellor's office to press home a four-point demand, including expulsion of some BCL leaders for “harassing” female students a few days ago. At least 50 students and two campus-based journalists were injured in the second such attack by the pro-Awami League student body in just eight days. BCL General Secretary SM Jakir Hossain and its DU unit President Abid Al Hasan led the attack to “rescue” DU VC Prof Akhtaruzzaman, who was confined for around an hour in front of his office at the Registrar Building, demonstrators said. Of the injured, 24 took treatment at Dhaka Medical College Hospital. One sustained brain injuries while three to four might have to be admitted there, said Sanaul Hoque Sarker, a doctor at the DMCH. Several hundred BCL activists from almost all hall units and from other institutions took part in the attack, blocking all three gates of the building and beating up students at random with iron rods, cricket stumps and sticks, witnesses said. Female BCL activists were seen beating up female students in different rooms. "They surrounded us and attacked us from all sides without giving us any scope to speak," said Tajwar Mahmid Siam, a third-year student of mass communication and journalism. However, BCL President Saifur Rahman Sohag denied that they swooped on agitating students. “On the contrary, the demonstrators attacked us when we went to rescue the vice-chancellor,” he told a press briefing last night at the Madhur Canteen. The BCL also said leaders of different left-leaning organisations attacked them and harassed some of their female students. In a press release, the DU authorities also blamed the agitators for the episode, saying some “violent students and outsiders” besieged the VC's office. On January 11, students from different departments launched a protest, demanding that the DU cancel affiliation of seven colleges with it. Four days later, as part of their agitation, around 100 students staged a sit-in before the VC's office. But BCL men foiled their demo, allegedly after the VC called in the BCL men. They harassed the female students and assaulted Moshiur Rahman Sadik, coordinator of the protest. Later, the BCL men handed Sadik over to the university authorities who subsequently handed him over to the police. On January 17, students under the banner of "Students against repression" started a fresh protest, demanding punishment of the BCL men for the assault. That day the agitating students broke down a gate of the Arts Building and kept the proctor confined inside his office for four hours. Later, the VC assured them of meeting their demands and formed a committee to investigate the January 15 incident. The next day, the university authorities filed a case against 50 unnamed students for breaking down the gate and formed a committee to probe the incident, fuelling the protest. "BEAT US MERCILESSLY" Yesterday, the students first formed a human chain on the base of Aparajeyo Bangla and then brought out a procession on the campus to press home their four-point demand -- punishment of BCL men for the January 15 incident, withdrawal of the case, removal of the proctor for his alleged anti-student stance and solve the crisis over the affiliation of seven colleges. Around 12:00pm, they besieged the VC's office after breaking down three gates -- the main entrance of the Registrar Building and two others inside. The VC was holding a meeting inside. They wanted the VC to assure them of taking steps to meet their demands. But as he was leaving his office around 2:30pm without talking to the students, the protestors blocked his way, and placed their demands. The VC then assured them of taking action regarding the January 15 assault following due process, and said it would take time. “All our activities will be conducted as per the University Ordinance of 1973. There will be no deviation from the rule of law,” he said. The students insisted that the case be withdrawn and Proctor Prof AKM Golam Rabbani removed immediately. But the VC did not make any clear statement, and kept saying the same thing. The students kept him confined there.
