2. in bareilly, where muslims protested and caused riots becz of kawadia .. it caused a long time curfew in bareilly.
3. lucknow - over burma muslims , where they tried to destroy Lord Budha statue. same time allahabad was also affected but at small level.
4. In ghazibad- u ll not find any record. this was small conflict, where on janmashtami, some muslims guys molested hindu girl and caused problem, funny thing was muslims were againt the music which temple usually play on janmashtami. and 1 more interesting thing, police did not registered case against any these people but registered case on the shopkeepers, who were there.
5. pratapgarh rape case- where muslims youth grouped raped and killed lower caste teen girl. and cause communal tension.
