A group which claims to be supporters of Prime Minister Najib Abdul Razak has threatened to gather tens of thousands to protest against the Bersih 4 rally come Aug 29.

Calling itself 'Gabungan NGO-NGO Malaysia', the group also said it would gather in front of Bersih chairperson Maria Chin Abdullah's house if the rally goes ahead as planned.

"They will face 30,000 people against the rally if they continue with it," said the coalition's leader Jamal Mohd Yunos ( photo ).

"We will also not hesitate to gather 6,000 to 7,000 people to open up stalls in front of Maria's house."

The group, which protested today at Jalan Masjid India, had brought along a cardboard cutout of Maria.

The 30 or so protesters, who wore yellow t-shirts with the words 'Kita menyokong Perdana Menteri (We support the Prime Minister)', later poured a red liquid to resemble blood on top of the cutout.

The cutout was then dumped into a rubbish bin after it was stomped on by the protesters.

Jamal said action must be taken against organisers as previous rallies had affected the country's peace and image in the eyes of tourists.

He also demanded that the Bersih rally organisers declare the details of funding they received for the rally, claiming that protesters were paid to participate in the rally.

He, however, declined to reveal the individuals involved, citing "safety concerns".
