"The Center is the epicenter of those who make baseless allegations against His Holiness Dalai Lama and the Tibetan Government-in-exile in the name of demonic deity Dolgyal," the GTV said in a statement released after their protest.
The statement said "over 30 demonstrators of Global Tibetan Volunteers for Truth (GTVT) distributed about 500 booklets about Dolgyal and some 3000 pamphlets among the public During that the protest."
The organiser said that "the purpose of the demonstration was to protest against the misdeeds done by the Dolgyal groups e.g, the harmful mission that they are doing to Buddhism, to the struggles of Tibetan freedom and defamation of His Holiness."
They also said that "It was also aimed to inform the people of the world in general England in particular about the real truth about Dolgyal and it's followers and to expose how they are deceiving people using the names of Jey Tsongkhapa and Buddha."
"The demonstrators have demanded the immediate stoppage of the harmful deeds against Tibetans and Buddhism by NKT or Shugden groups," it added.
"When the people around the saw the real face of the Center and it's followers, they thanked the demonstrators for giving correct information the Dolgyal."
"Because Dolgyal groups had started making the allegations from London, so the Global Tibetans Volunteers for Truth has also started protesting from the same place," it further stressed.
"It was strongly iterate that until the Dolgyal groups stop misinforming and making baseless allegations, the members of the GTVT will never stop protesting against them," the group wrote, adding, "With this declaration, the procession went fruitful and victorious one."
Protesters from NKT staged protests against His Holiness the Dalai Lama as he lands in the country. The protesters lined the streets in London, banging drums and shouting slogans. They claim Shugden followers are being persecuted and His Holiness the Dalai Lama has failed to take a stance.
"I suppose you are asking about the Shugden question, a controversy that has been going on for nearly 400 years. However, it's only come to prominence in the last 80 years or so,"
His Holiness said in response to a question from a woman from the audience at his talk on September 19 at the O2 arena.
"In my own case, while I propitiated this spirit, I had no religious freedom. I only gained that freedom once I understood its nature and background and stopped that practice."
"You have no religious freedom when you worship this spirit. It is very much sectarian. Since then it's been my duty to make this clear to others. If you want to pay attention to what I have to say, that's up to you," His Holiness added.
