Three persons were killed in police firing and 60 policemen were injured after violence broke out in Bengaluru on Tuesday night over an offensive Facebook post allegedly by the relative of a Congress MLA. 145 people have been arrested for violence, stone-throwing and assault on police personnel. Protesters set around two dozen cars on fire and surrounded Congress MLA Srinivas Murthy's house in the Karnataka capital. Mr Murthy's nephew Naveen, who allegedly posted the now-deleted message on Facebook, has been arrested.
