Amid simmering tension at the Karnataka-Maharashtra border where huge protests were planned today for the last winter session of the BS Bommai government in Karnataka, Nationalist Congress Party and Shiv Sena leaders were detained and taken into preventive custody. NCP's Hasan Mushrif, and Shiv Sena's Kolhapur district president Vijay Devane, were detained today while trying to enter Karnataka's Belagavi, the centre of the decades-old border dispute where the 10-day winter session of the Karnataka Assembly is being held. This will be the state's last winter session before it goes to polls next year.
