Garment workers went on the rampage at Salna in Gazipur yesterday following rumours that law enforcement agencies beat up and detained some of their colleagues.

Sources said about 4,000 workers of Shamoly Garment staged the sit-in inside the factory for realising their four-point demand, including an increase in wages and bonuses to which the factory management conceded.

The workers, however, turned violent as rumours spread that Rab personnel beat up and confined some of the workers on their way back home, damaging the factory's windowpanes and six vehicles.

The workers also damaged the main gate of the factory and doors of the administrative office.

Army soldiers later rushed to the spot and managed to calm the workers through discussions.

Deputy Director of Rab 11 Major Maksudul Bari denied beating up of any garment workers. Security has been beefed up at the factory.
