With the State government yet to take concrete measures on preventing child sexual assaults, Congress president Sonia Gandhi has written to Chief Minister Siddaramaiah expressing concern over the issue. Ms. Gandhi has sought a report on the measures initiated to protect vulnerable children. The letter follows the sexual assault on a girl in a school in Indiranagar on August 3. The State government started compiling a report after the August 3 incident and has sought details on the measures initiated by different departments.
