Visuals of the police forcibly arresting a Sikh man during the BJP's mega protest in Kolkata on Thursday have set off a major controversy with the party accusing the cops of hurting religious sentiments by pulling off the turban of 43-year-old Balwinder Singh, a resident of Bhatinda, during a clash at Howrah maidan. The controversy gathered so much momentum on social media, even cricketer Harbajan Singh has tweeted, tagging Chief Minister Mamata Banerjee, to say, "Please look into the matter. This just isn't done."
