Two men died while attempting to rescue a mason who fell ill inside an under-construction septic tank in Raozan upazila of Chattogram on Friday afternoon. The incident occurred around 1 p.m. at the house of the late Kartik Das in Jhikuti Para area of Noapara Union. The deceased were identified as Pradip Das, 38, and Samiran Das, 28, who were brothers-in-law. The injured mason, Shah Alam, was admitted to Chattogram Medical College Hospital.

According to family members, Shah Alam became unconscious while working inside the tank. Pradip Das entered to rescue him and managed to lift him up but then lost consciousness himself. Samiran Das then went down to help but also failed to come out. Fire service personnel later recovered all three victims. Police confirmed that the two men were declared dead at a local hospital.

Authorities suspect the deaths may have been caused by toxic gases and lack of oxygen inside the closed tank, though some locals attributed the tragedy to supernatural causes.
