Union Minister Narayan Rane was arrested today over his comment on slapping Maharashtra Chief Minister Uddhav Thackeray for what he called his "ignorance of the year India won Independence". He was, however, granted bail by a court in Mahad late in the night. Mr Rane, a BJP leader who joined Prime Minister Narendra Modi's cabinet in July as Minister for Micro, Small and Medium Enterprises, is the first central minister to be arrested in 20 years. His arrest has become the new flashpoint between allies-turned-rivals Sena and BJP.
