Incensed with a letter of demand sent to him by pro-electoral reform NGO Bersih, red-shirt leader Jamal Md Yunos tore the document and flushed it down a toilet, calling it filth.

The letter of demand from Bersih asked that Jamal apologise within 48 hours for alleging that the movement had been infiltrated by Islamic State and intends to use the Bersih 5 rally to topple the government.

"I see this summons as filth," he said while tearing and flushing down the legal document.

Earlier, Jamal had called for a press conference at the Selangor Umno building in Shah Alam at around 4.45pm.

However, as soon as reporters arrived at the building, he led them to a nearby lavatory where he proceeded to shred the legal document and throw pieces of it into the toilet bowl.
