The Betawi Brotherhood Forum continued to allege on Saturday that Greenpeace's presence in Indonesia violates the law, and was seeking to compel the environmental organization to report itself to the Jakarta administration, Berita Jakarta reported.

The Betawi Brotherhood Forum, known as the FBR, is a vigilante group known for employing thug-like tactics. On Saturday, the FBR's head, K.H. Lutfi Hakim, said the group would continue to put pressure on Greenpeace because its presence violated the law.

"We will keep controlling Indonesia Greenpeace actions until they report to Jakarta," Lutfi said during a 10th anniversary celebration for the FBR in Senayan, Central Jakarta.

According to Lutfi, the NGO's activities in Indonesia could be seen as breaking Indonesian law and violating the country's sovereignty, an allegation also leveled by some local politicians.

On July 14, about 100 members of the group staged a noisy rally outside Greenpeace's Jakarta headquarters, protesting what they said were the environmental group's attempts to spread negative stories about Indonesian companies, endangering local jobs.

Greenpeace has maintained that its works in Indonesia are well within the law and that the organization is already registered with the Justice and Human Rights Ministry.

Also on Saturday, Jakarta Governor Fauzi Bowo told the roughly 10,000 FBR members at the anniversary rally that he was anticipating the group providing security during the Southeast Asian Games to be held in Jakarta in November.
