When thousands of people gather under one roof, there is always a danger of security breach.
Keeping this in mind, Delhi police deployed sniffer dogs and bomb detection teams at the Ramlila ground on the first day of the fast led by Baba Ramdev on Thursday.
Bag scanners were set up at all entry points coupled with heavy police deployment, including Rapid Action Force, in and outside the venue.
"There's always a security threat as such protests with massive crowds are vulnerable targets. Seven police companies, around 500 policemen, have been deployed," said a senior police officer.
However, such arrangements couldn't stop thieves from entering the grounds. Four to five people, who allegedly stole people's mobile phones, were caught by volunteers but were told by Ramdev not to punish them.
"Give lighter punishments to these small thieves. Catch bigger thieves," the yoga guru said, referring to people stashing black money in foreign banks.
Volunteers said over 50 mobile phones are reported to have been stolen from the Ramlila Maidan after the fast began this morning.
Also, the medical stalls at the ground were teeming with Ramdev supporters complaining about diarrhoea and headaches. More than 2,000 protestors who had come to support the cause were found to have registered at the medical stalls.
"We have got all basic medicines and an ambulance is also stationed here," said a doctor at the medical stall.
Around 5,000 people registered to support Ramdev's cause and donations poured in lakhs. One such anonymous donor gave Rs. 7.5 lakh.
