LUCKNOW (AFP) - Activists from Indias ruling party protested Thursday over the arrest of a party leader for allegedly suggesting a high-ranking politician should be raped to better understand the crime. Rita Bahuguna Joshi, who heads the ruling Congress in Indias most populous state, Uttar Pradesh, was arrested on Wednesday and her house burned down after her supposed comments about state Chief Minister Mayawati Kumari. Joshis remarks triggered statewide protests by supporters of Mayawatis Bahujan Samajwadi Party, who set fire to the Congress leaders house in Lucknow. She was later arrested on a charge of making inflammatory remarks about members of a lower caste. Mayawati is a member of the dalit community - the lowest caste order in India and previously known as untouchables. On Thursday, it was the Congress supporters who took to the streets. We will resort to all forms of protests including road blocks and hunger strikes. Our leader has been arrested and attacked, a senior Congress member told AFP. Joshis comments allegedly included criticism of Mayawati for handing out financial compensation to lower caste victims of rape and murder.
