The volunteer, donning a Team Anna T-shirt and cap and carrying a mega phone, surfaced at the media enclosure of the protest site at Jantar Mantar around 12:15 PM when a close aide of Ramdev was speaking on black money.
The youth started speaking through his megaphone demanding that he be heard by both Hazare and Ramdev but was prevented by Ramdev's volunteers.
While he was being pacified, he alleged that he was mistreated by a prominent Team Anna member Arvind Kejriwal.
He then pulled out a bottle of a kerosene and poured on him. While he took a lighter to set himself on fire, the volunteers and some media persons snatched the lighter from him.
He was heard telling that he would commit suicide at home if he was not heard by Hazare and Ramdev or allowed to commit suicide in Jantar Mantar. He was whisked away by police.
Kejriwal could not be contacted as he was on the dais on fast along with Hazare and Ramdev.
