Shahriar Alam Samyo was assaulted after a verbal altercation with a group of known drug dealers at the food court in Suhrawardy Udyan on the night of May 13, according to DMP Commissioner Sheikh Mohammad Sajjat Ali. The dispute reportedly began when Samyo asked to see their electric vehicle, often used for self-defense. The altercation escalated, and a drug dealer named Rabbi attacked Samyo with a Swiss gear knife, injuring his leg. The Detective Branch has arrested eight more suspects, bringing the total number of arrests in connection with the murder to eleven.
