Panic gripped them as the joint forces recently arrested BCL Orginising Secretary Tuhin Reza from the campus allegedly for organising a protest against the arrest of Awami League President Sheikh Hasina.

Tuhin, however, was released two days later, sources said.

The joint forces raided two dormitories at midnight and searched for BCL leaders and activists in the wake of BCL demonstrations held in front of the arts faculty building.

The law enforcers also raided the house of RU BCL Joint Secretary Ujjal near the university area but could not find him, the sources said.

Meanwhile, the university authorities have allowed the joint forces to conduct raids on any dormitory in order to maintain law and order.

The arrest and raids have prompted many top BCL leaders and activists to leave the campus, sources said.

Expressing concern over such situation, A BCL worker said, "We might not hold August 15 mourning programme as most of the leaders left the campus fearing arrest."

The law enforcers have also raided residences of students near the university and in the city several times to hunt down 'listed' activists of BCL, who violated the state of emergency by taking part in the demonstration and demanding resignation of the law adviser, the sources said.

They also said the police and intelligence branches recently prepared a list of leaders and activists of BCL who violated the state of emergency and orginised demonstration on the campus.

Some students said that the police have also interrogated them to inquire about BCL leaders and activists.

When contacted, RU BCL General Secretary Ayeen Uddin said, "Our August 15 programme has become uncertain as most leaders and activists are now passing days in fear."
