Congress and BJP destabilised the peace of Karnataka, alleged former state Chief Minister and Janata Dal (Secular) leader HD Kumaraswamy following the murder of 28-year-old Bajrang Dal activist Harsha in Shivamogga. “Last week, when the Karavali issue (hijab row) started, I predicted that this kind of development will take place. We saw the death of a boy. This is the achievement of Congress and BJP. They destabilised the peace of this state. They wanted this kind of incident,” he added.
