Bersih chairperson Maria Chin has revealed that those who issued a death threat against her, also sent images of her three sons' MyKad.

"I don't know how they got hold of the photos. This just shows how desperate they are.

"They are using the name of Islam to spread slander and scare us," she told reporters after filing a report with the Petaling Jaya district police headquarters this evening.

Maria had received the threat via her mobile phone, and the message had stated that it was a warning from Malaysian Islamic State operatives.
