Earlier they took part in a procession at the same place demanding unconditional release of AL President Sheikh Hasina.

The demonstration was part of the BCL's weeklong programme announced last week. They also held demonstrations at different districts across the country.

This is the first time an adviser's effigy was burnt when all political activities including processions are banned in the state of emergency.

Sources said about 15 BCL activists led by DU unit of BCL President Sohel Rana Tipu brought out a brief procession in front of the Institute of Social Welfare and Research at around 9:40am dodging the vigilance of law enforcement agencies.

They chanted slogans demanding release of Hasina and resignation of the law adviser for his 'biased activities'.

Later they burnt the effigy of Mainul for 'breaching the oath of office by favouring some specific groups'.

The demonstrators managed to flee before members of the law enforcement agencies reached the spot.

Since the detention of Hasina, the BCL has adopted a strategy to hold programmes at different places of the campus eluding the law enforcement agencies' surveillance.

BCL President Mahmud Hasan Ripon said they demanded Mainul's resignation as he lost his right to stay in office. They will continue their programmes until the release of Hasina, he added.

UNB adds: Some 30 students have been sued for burning an effigy of Law and Information Adviser Mainul Hosein on the Dhaka University campus yesterday.

The officer-in-charge (OC) of New Market Police Station said the case was filed under the Emergency Rules.
