KUALA LUMPUR - Curious Malaysians took on the role of investigating the Prime Minister's wife Datin Serin Rosmah Mansor yesterday, transferring RM1 (S$0.36) to a bank account which a news website alleged belonged to her.

On Thursday, whistleblower site The Sarawak Report, claiming documents from an investigation into the financial affairs of state investor 1Malaysia Development Berhad (1MDB), alleged that a man had made cash deposits into the account of Madam Rosmah at a Malaysian bank totalling RM2 million (S$713,000) between February and April this year.

The site also published Madam Rosmah's alleged bank account details, telephone numbers, address and her old identity card number.

Several vigilante Malaysians sprung into action to verify if the bank account was indeed hers, reported the Malaysian Insider.

On Friday, several social media users posted pictures of their online and cash deposit machine transactions online, noting that the name on the bank account number published by the Sarawak Report belonged to "Rosmah binte Mansor."

Twitter user @kuangkeng said that he had deposited RM1, the minimum amount needed to make a transfer, into the "Rosmah" account and shared a picture of the transaction.

"I just transferred RM1 to confirm the Affin bank account exposed by @sarawak_report belongs to a Rosmah Binte Mansor," he tweeted.

Haziq Asyraf Jr, posting through his Twitter handle @Haziq_Escobar also made a similar transaction, and posted the photo.

"DO YOU KNOW: Testing a RM1 money transfer into Mother Rosmah Mansor's account), he tweeted in Malay.

While many social media users were amused, others lamented that the account was "raking it in" with the number of Malaysians transferring RM1 to her account, reported the Malaysian Insider.

Twitter user Bash Rahman posted: "Account could have an additional RM1 million by the end of the day after all the RM1.00 deposits. - Eric"
