Heavy smoke choked residents of Iblur and Bellandur in Bengaluru as fire broke out on Thursday close to the lake spreading rapidly. The already polluted lake fuelled the fire sending up thick clouds of smoke. The local police have issued an advisory for heavy smoke to the residents. Locals allege that illegal garbage burning and unchecked pollutants entering the water bodies led to the fire and it spreading. Despite multiple pleas, the BBMP has failed to bring the pollution in the lake under control.
