Police officer HM Shaheen reported that the mob, numbering 200‑250, stormed Debhata Upazila Health Complex at 8:40 p.m. after the patient had been rescued at 4:40 p.m. and admitted.
The audio clips that spread on social media were said to contain remarks that offended religious sentiments, local resident Khairul Alam told Prothom Alo.
Shamim’s elder brother Abdul Jalil told The Daily Star that a year earlier he had been targeted by a gang known as the “Ogyan Party,” and that the victim’s behaviour had changed since then.
The family said the man had attempted suicide by ingesting poison a few days earlier, and that he had been mentally ill for several days.
Police have opened a criminal case and are investigating the mob’s actions. Authorities plan to file charges under Section 302 of the Penal Code for murder and Section 505 for incitement.
