Supporters of arch-rivals East Bengal and Mohun Bagan gathered near the Salt Lake stadium, the venue of the cancelled Kolkata Derby, on Sunday evening in a rare show of camaraderie to protest the alleged rape and murder of a doctor at RG Kar Medical College and Hospital. Over a hundred supporters of the two clubs initially gathered outside the stadium with placards and posters even as a Durand Cup match between the two most-followed football clubs of the country was cancelled with police citing concerns over the law and order situation.
