Faisal Karim Masud, the prime suspect in the murder of Bangladeshi student leader Osman Hadi, has denied involvement in a viral video, claiming the case against him is fabricated. Masud alleges a radical political group is responsible and states he was in Dubai during the time of the killing, contradicting police claims. Hadi was shot in Dhaka earlier in December while launching his election campaign. Police have identified suspects but not yet made arrests.
