Authorities tightened security around New Delhi's Jantar Mantar, a designated public protest ground enclosed by police barricades, where activist Sonam Wangchuk has been camped along with students and Cockroach Party activists who demand the resignation of Education Minister Dharmendra Pradhan, after allegations that exam papers were leaked in advance.
The movement also seeks sweeping reforms to the examination system and compensation for families of students who died by suicide over the leaks or exam results.
The 59-year-old engineer and education reformer's strike has become a rallying point for the party, which began in May after Supreme Court Chief Justice Surya Kant compared some unemployed young people to "cockroaches" during a hearing on another issue.
Supporters embraced the insult as a badge of resilience, turning it into a satirical political campaign that amassed more than 21 million Instagram followers in a few days.
Delhi Police said Wangchuk was taken to hospital on Saturday after his health worsened during the hunger strike, and that a brief commotion occurred when some protesters tried to block the move.
Sachin Sharma, a deputy commissioner of police, said Wangchuk's hospitalisation was carried out following medical advice and a court directive.
"Mr Sonam Wangchuk has been taken from here to an appropriate government hospital, a much-needed medical intervention, under medical supervision," Sharma said.
The Cockroach Party said in a social media post that the government "forcefully abducted" Wangchuk "without his or his family's consent".
Shortly after the incident, Abhijeet Dipke, a Boston University student and founder of the Cockroach Party, announced he would begin a hunger strike.
Dipke told The Associated Press at the protest ground that police used force while removing Wangchuk and alleged he was "kidnapped by the police like criminals and goons" after "covering him in sheets".
The party founder reaffirmed the movement's plan to march to India's parliament, scheduled for Monday, when its session begins.
"The resolve and the movement will only get stronger from here," Dipke said.
Authorities deployed additional police and paramilitary soldiers and erected barricades around Jantar Mantar.
Police said the heightened security measures were precautionary and urged protesters to co-operate with authorities.
