Various platforms including indigenous groups, literary and recitation organisations demanded justice for Lakingme Chakma and said her killers should be brought to book without any delay.
They made the demand during a candle-light vigil commemorating Lakingme Chakma at Cheragi intersectioin of the port city.
Rashed Hasan, joint general secretary of Bangladesh Abittri Somonnoy Parishad questioned why indigenous people have to take to the streets repeatedly even though the constitution has made sure everyone will be treated equally.
Rashed said the abduction and murder of Lakingme added to the collective injustice being rendered to ethnic people.
"This (injustice) must stop here and the killers must be brought to book without any delay and hesitation", he said.
Sharif Chowhan, convener of Ganajagoron Mancha, Chattogram said Lakingme was abducted and forced to convert her religion which is a blatant violation of human rights.
He urged the government to ensure justice to the victim's family so that everyone can feel a sense of belonging to this country.
Pahari Chattro Parishad, Bangladesh Muktijuddo Gobesona Kendro, Bangladesh Minority Watch, leftist organisation attended the programme.
14-year-old Lakingme Chakma was abducted, converted and married off to one of her abductors, and eventually murdered in Teknaf of Cox's Bazar last year.
