Kolkata, June 21 -- The Bharatiya Janata Party's West Bengal unit president and Union minister of state Sukanta Majumdar and Rajat Subhra Bandyopadhyay, a UK-based doctor, were detained by Kolkata police and taken to the Lalbazar police headquarters in front of the media on Friday afternoon on charges of disrupting traffic moments after they held a brief roadside interaction in Kolkata, sparking a political uproar. Majumdar and Bandyopadhyay, a British passport holder with roots in South Kolkata, were later released.The BJP alleged that the detentions were linked to the doctor's now-famous confrontation with Chief Minister Mamata Banerjee during a lecture at Kellogg College, Oxford University, in March. Bandyopadhyay had asked the CM to name a single major industry that had come to Bengal during her tenure, following which chaos ensued and university security had to intervene. After his release, Majumdar alleged that he was "arrested" at the behest of the CM and TMC national general secretary Abhishek Banerjee and that democracy is in peril in West Bengal. "I don't know the reason behind my arrest. I will move the court (against the arrest) and write to the Union home minister. I want to know the necessity behind having so much security on the road next to the residence of a TMC MP who does not enjoy any official position. Why my movement in that area be restricted?" Majumdar told reporters. Responding to the incident, the Trinamool Congress defended the police action, accusing the BJP of "stage-managing provocations." "The BJP is creating deliberate provocations in sensitive areas. The doctor in question has a track record of inciting controversies," TMC spokesperson Kunal Ghosh said....
