[14][15] On 24 December 2019, police filed a case against Shahbag police station and arrested the then general secretary of the Muktijuddah Manch Yasin Arafat Turi and the office secretary Mehedi Hasan Shanto on charges of involvement in the attack.

Despite the lack of any concrete evidence, the court denied him bail and ordered him sent to jail after a 5 day remand.

Upon release from remand on 26 July, however, it was apparent that Nur had been severely tortured and beaten, as he appeared in significant pain and unable to stand without assistance.

In Nur's situation, he was unaccounted for for 40 hours before being brought to court, according to his wife, which raises questions about the legality of his detention.

Ramadan urged the Bangladesh government to investigate the matter, questioning whether Nur's denial of the meetings would suffice for the country's security forces.
