The deaths of ready-made garment workers during different labour movements, mostly for wage hikes, have remained uninvestigated for years.
Labour rights activists said that due to no justice for the killing of workers such incidents were on the rise, resulting in deaths of more workers.
At least 10 garment workers have been killed in labour unrest in the past 10 years, including five this year.
No case was filed in most of the incidents, while police filed Unnatural Death cases in some incidents.
Families of the victims alleged that police and factory management dissuaded them from filing cases.
