The High Court yesterday asked the government to remove Tridev Roy's name from all structures in Khagrachhari and elsewhere within 90 days.
Tridev Roy was the 50th Raja of the Chakma Circle a role he abdicated in 1971 during the Liberation War in favour of Pakistan.
The order was passed on the grounds of allegations made against him as a Pakistan sympathiser and collaborator of the Pakistani Army and structures and institutions should not bear his name.
The High Court had a previously ordered the removal of the names of all collaborators from structures in Bangladesh.
Yesterday's order was passed by a High Court bench of Justice Quazi Rezaul Haque and Justice Mohammad Ullah on a writ petition filed by two freedom fighters.
It also issued a ruling asking the government to explain why it should not be ordered to remove Tridev's name from all structures. The government has four weeks to respond to the ruling.
Badiuzzaman Saudagar of Rangamati and Helal Uddin from Khagrachhari filed the petition on Sunday.
Lawyer of the petitioners, Sharif Ahmed said during the Liberation War, Tridev Roy sided with the Pakistani Army and committed crimes against humanity. He is known as anti-liberation person in the Chittagong Hill tracks, especially in Khagrachari but in Khagrachari there are roads, schools and areas named after him.
After the independence he fled to Pakistan and was a career diplomat before his death in Islamabad in 2012 from a cardiac arrest.
