The police on Saturday stopped a BJP rally led by its West Bengal unit chief Sukanta Majumdar and detained him along with several other party leaders when they tried to take out the protest march to a law college in the city, where a student was allegedly gang-raped, a senior officer said.

The rally was not allowed to proceed towards the South Calcutta Law College where the 24-year-old student was allegedly gang raped by her two seniors and an alumnus of the institution on June 25.

“The rally was stopped at Gariahat crossing in south Kolkata, and Majumdar and several other BJP leaders were detained. They were taken to the Kolkata Police headquarters in Lalbazar,” the senior officer said.
