According to tweets from people across, atleast 500 people dressed in civil dress have been deployed and many claimed to be from the Rapid Action Force (RAF) have been spread across Anna's fast venue.
Reports also suggest that the Gandhian Crusader will be forcibly evicted and hospitalised if he does not end his fast tonight.
Meanwhile, Anna Hazare has given an ultimatum of 4 days to the government to draft the Lokpal Bill.
Earlier, Baba Ramdev also offered to take over Anna's fast at Ramlila Maidan if the Gandhian Crusader is taken to hospital.
The yoga guru who was evicted from the same venue on Jun 4 by the police was back to Ramlila Maidan, this time to support Anna Hazare.
Ramdev expressed his solidarity with Anna in his fight against corruption and demanded that the system be “transparent".
