Rock Collapse at Bengaluru Stone Quarry Kills Seven to Nine Labourers, Investigation UnderwayPreviousNext

A massive rock collapse at a stone quarry in Madapattana, Bengaluru South Taluk, on July 2 resulted in the deaths of seven to nine daily-wage labourers, mostly migrants from Bihar and Assam. The incident occurred during quarrying operations when a large boulder fell from about 40 feet, trapping workers beneath. Several others were injured and hospitalized. Authorities have launched rescue and investigation efforts to determine causes and check for safety violations. Political leaders expressed grief and called for strict action against quarry owners if negligence is found.
