They urged taking swift actions for delivering justice.
The call was made at a discussion arranged by HWF at Jatiya Press Club marking the 23rd anniversary of Kalpana’s abduction.
They urged everyone to launch a joint movement against abduction.
Leaders of different organisations claimed that miscreants abducted Kalpana to silence her voice for democratic movement in the hills.
Barrister Jyotirmoy Barua said trial for Kalpana’s abduction never took place because the investigation is still incomplete.
“Whoever is in charge of the investigation asks for more time,” he said.
Biplobi Workers Party General Secretary Saiful Haque said they were optimistic that after the Chittagong Hill Tracts Peace Accord was signed in 1997, those who had been kidnapped, including Kalpana, would be found.
“But that didn’t happen in 22 years,” he said.
Kalpana, organising secretary of HWF, was kidnapped on June 12, 1996 from New Lalyaghona of Baghaichhari, Rangamati. Her brother Kalindi Kumar Chakma filed a case several days later.
In a joint statement, HWF leaders condemned the repeated incidents of violence against women including rape and murder of Sohagi Jahan Tanu and the killing of Feni madrasa student Nusrat Jahan Rafi.
The speakers also urged the government to take steps for finding abducted UPDF leader Michael Chakma and other political leaders.
They also demanded the removal of 11-point directives issued by the Home Ministry for the CHT.
Left Democratic Alliance leader Bazlur Rashid Firoz, Socialist Party of Bangladesh (Marxist) central leader Manas Nandi, Barrister Sadia Arman, Bangladesh Student Federation Organising Secretary Mitu Sarker, Socialist Student Front President Imran Habib Rumon, among others, spoke at the event chaired by HWF President Nirupa Chakma.
