He said he was in jail for 42 days in Mangalore before being released on conditional bail by Karnataka High Court. He was a critic of the Bharatiya Janata Party calling it a regime to "save the government from further embarrassment after the church attacks and on instructions from the Sangh Parivar leaders."
