Two brothers, M. Abinesh (17) and M. Mukesh (15), were killed on Friday morning when the roof of a dilapidated house collapsed on them in Elangadu village near Vandavasi town, Tiruvannamalai district. The boys, studying in Classes 11 and 9 at Government Boys Higher Secondary School in Vandavasi, were staying with their grandmother, K. Ponnammal (65), to be closer to school. Around 8 a.m., the brothers, their uncle M. Seetharaman (38), and his son S. Sriram (8) went to demolish another house owned by their grandmother. While Seetharaman tried removing parts of the roof, it suddenly gave way and fell on the boys inside. Both Abinesh and Mukesh died instantly. Sriram suffered minor injuries. Local residents rescued them quickly. The Ponnur police and Vandavasi firefighters arrived soon after. The bodies were taken to Government Taluk Hospital, Vandavasi, for postmortem. A police case is registered, and investigations are ongoing.
