Seven separate complaints were filed against at least 53 persons with the International Crimes Tribunal yesterday, over allegations of torture and enforced disappearance of seven activists of Islami Chhatra Shibir.

The accused include members of law enforcement agencies, as well as activists of Awami League, Jubo League and Chhatra League.

The complainants are: Johnny Islam, a Shibir activist from Rajshahi University; Abdul Karim and Saiful Islam, of Shibir's Banshkhali and Rangunia units respectively in Chattogram; Nurul Amin, former president of Shibir's Vatara unit in Dhaka; Alamgir Hossain of Bogura's Sherpur; Delwar Hossain of Noakhali; and elder brother of Kamaruzzaman, former president of a union level unit of Shibir in Jhenaidah's Ratanhat.

Abdullah Al Noman, prosecutor of ICT, confirmed the matter.

Saiful, one of the complainants, recounted his harrowing ordeal during captivity at a press briefing on ICT premises yesterday.

"I was blindfolded and had my hands tied 24 hours a day. They did not allow me to use the bathroom, forcing me to urinate in the same bottle used for drinking water. I had to empty the bottle, then reuse it for drinking," he said.

He also said that they only allowed him a minute or two to eat after serving food.

"If I failed to eat during the limited time, they used to beat me, and then take away the food," he added.

Abdullah Al Noman, Shibir's law affairs secretary, said, "Four complainants were maimed or lost limbs after being tortured by law enforcers. Kamaruzzaman, who disappeared in 2017, remains unaccounted for. One individual returned after three and a half years of disappearance, while another after being missing for three and a half months."

So far 17 similar complaints have been filed with the tribunal, involving 16 Shibir activists and one non-affiliated student, he added.
