Wangchuk, 59, began the indefinite hunger strike on June 28 in solidarity with the youth-led Cockroach Janta Party (CJP), which is calling for Education Minister Dharmendra Pradhan to step down over exam paper leaks in May that affected millions of students.
His protest has become one of the most prominent public challenges to Prime Minister Narendra Modi s government, attracting widespread support across India and gaining millions of views on social media.
Television footage on Saturday showed dozens of police and security personnel arriving at the protest site before Wangchuk was taken away. Large white cloth sheets were held around the stage, and Wangchuk was not visible in the footage.
Delhi Deputy Commissioner of Police Sachin Sharma said the activist had been moved to hospital in compliance with a court order and on medical advice.
"In compliance with the court s order, and based on health conditions and medical advice, Mr Sonam Wangchuk has been moved to an appropriate government hospital for much-needed medical intervention and is currently under medical supervision," Sharma told reporters.
On Thursday, the Delhi High Court directed authorities to closely monitor Wangchuk s health and intervene if necessary after a petition sought medical intervention as his condition weakened.
Police also cleared supporters of the Cockroach Janta Party who had been staging a sit-in at the protest venue. Television footage showed police removing several protesters, including women.
According to ANI News, Wangchuk remained conscious and his vital signs were stable after being admitted to hospital.
CJP founder Abhijeet Dipke accused police of forcibly removing the activist.
"They dragged Sonam Sir away... a 60-year-old man, who had been on a hunger strike for 20 days and hadn t eaten a thing, was forcibly dragged away by the Delhi Police. We have no idea where they have taken him," Dipke said.
Following Wangchuk s removal, Dipke announced that he had also begun an indefinite hunger strike and said CJP supporters would march towards the Indian Parliament on July 20, when the monsoon session begins, to press for the education minister s resignation and broader examination reforms.
Wangchuk has remained at the centre of the protest movement, spending the past three weeks on a mattress placed on the main stage while supporters gathered around him.
The activist, who belongs to the Himalayan region of Ladakh, was arrested last year after India s government accused him of inciting violence during protests in the territory. He spent nearly six months in jail before being released in March and has denied the allegations, saying the unrest reflected public frustration with the federal government.
Speaking to Reuters on the third day of his fast, Wangchuk had said he intended to continue the hunger strike for six weeks unless his demands were addressed.
"But hopefully, we don t have to go that far. A sensitive government in a democracy listens to the pains of the people, and I hope they will take action," he had said.
The hunger strike has drawn widespread attention online, with more than 100,000 Instagram reels urging Wangchuk to end his fast.
