The city police registered two cases against Bharatiya Jana Shakti founder-president and the former Union Minister Uma Bharti on the charges of instigating communal disharmony and threatening to commit suicide on Saturday night.

Police source said Miss Uma had allegedly said in a demonstration held in the city on Saturday evening that BJS party workers, including herself, were ready to sacrifice their lives to protect Ramar Sethu at any cost.

Tamil Nadu government should look for an alternative route to Ramar Sethu, she added. The BJS chief left for Bhopal from Tiruchirapalli on Saturday night.
