MUMBAI, July 23 -- Police in Mumbai are digitally tracking student protestors, demanding that they share live locations, and even turning up at their homes to pressure them to stay away from the Cockroach Janta Party-led mass agitation that has now spread to several cities and even overseas. And, yet, refusing to back down, around 2,500 youth, students and activists filled the narrow lanes near Shivaji Park in Dadar, over 200 others turned up at Chembur and many more at Juhu, Colaba and Powai on Wednesday, day five of the agitation. Even as the mass detentions continued - over 400 protestors were rounded up on Wednesday - police admitted to the electronic surveillance, allegedly violating the Bhartiya Nyaya Sanhita (BNS) and Information Technology Act (IT Act), according to lawyers assisting the young protestors navigate the law. "On Wednesday, appeals had gone out to gather at Dr Babasaheb Ambedkar Garden in Chembur, at 1:00pm; in Juhu at 12:30pm and at Shivaji Park at 4:00pm," said a senior police officer. "As a preventive measure, we started detaining people who had participated in earlier protest gatherings and whose data was available with us. Some police stations warned past protestors to share live locations and stay at home," admitted the officer. Samya Korde, a lawyer representing many of the protestors, said police turned up at her Wadala home early on Wednesday and instructed her to stay indoors. Korde was detained and served a notice of appearance for protesting at Shivaji Park on Monday. "Electronic surveillance by the police is a violation of 'personal privacy' under the BNS and IT Act. It is also a violation of fundamental rights," alleged Korde. "People were also detained at railway and metro stations and not allowed to board trains. They even visited the homes of students who had been served notices earlier," she said. Sources cited the instance of a young man in Bhiwandi, who had participated in Monday's Shivaji Park protest. Four policemen allegedly turned up at this doorstep on Wednesday, warning him against attending further student gatherings. Advocate Vikrant Khare, who is also assisting the protestors, claimed that a few students who had not attended a single protest were picked up by the police on Wednesday. Police told HT they are also keeping tabs on individuals overseas. "Indian students studying abroad are gathering information, posting updates, and motivating students here," said an officer. At Shivaji Park, more than 2,500 people turned up for the protest. Shivaji Pawar, a 72-year-old Dadar resident who had stepped out to buy milk, found himself joining the procession and walking nearly 200 metres. "After destroying the careers of so many people, how can the government act as if nothing happened," Pawar said. In Colaba, veteran activist Tushar Gandhi and state Congress president Harshwardhan Sapkal were detained for around 90 minutes after a protest at Gandhi Bhavan....
