Despite Wangchuk's removal, AISA members and CJP founder Abhijeet Dipke continued the hunger strike, insisting the protest would not end until their demands were met.
Supporters and Opposition leaders condemned the police action, while Delhi Police said the hospital transfer followed medical advice and High Court directions.
With the 'Chalo Sansad' march scheduled for Monday, protesters said Wangchuk's hospitalisation had strengthened, rather than weakened, the movement.
