It breaks my heart to hear the government call my husband's murder an accident, said the wife of the senior police officer who was killed by a mob in Uttar Pradesh's Bulandshahr. "It's been 16 days and the main accused has still not been arrested. An SHO (station house officer) is killed on duty and they say he died of heart attack. I feel very sad for the man who lost his life in the line of duty," Rajini Singh, wife of Subodh Kumar Singh, told NDTV.
