Rapid Action Battalion (Rab) has arrested Kabir, a close aide of Faisal Karim Masud, the prime accused in the attempted murder of Osman Hadi.

Rab Media Wing Headquarters Wing Commander MZM Enthekhab Chowdhury confirmed the arrest to The Daily Star on Monday night, saying Kabir was detained as a suspected associate directly linked to the attack.

CCTV footage revealed that Faisal entered the Inqilab Cultural Centre with three others on December 4, where he was seen speaking with Hadi. The footage further shows Faisal attending a meeting with Hadi at the same venue on December 9.

The footage identifies Kabir as one of the men who accompanied Faisal to the Inqilab Cultural Centre on December 4.

Previously, Rab detained Faisal's wife Samia, his friend Monika, and his brother-in-law Shipu, in connection with the shooting of Hadi.
