City Harvest Church founder Kong Hee has spoken out against the hacker who attacked his wife Ho Yeow Sun's website on Monday.

He said he was "very concerned" that the hacker's statements "appear to have been intended to cause readers to influence and pre-judge the issues in the criminal proceedings that are presently on-going".

He said that while he and Ms Ho have been the subject of criticism over the years, "this episode is particularly malicious". The matter has been reported to the police, he said, adding that he hopes the authorities "will act to protect the integrity of the administration of justice, and take all necessary steps to find and stop the person or persons responsible for these malicious acts".

Ms Ho's website at www.heyaosun.com was the target of a cyber attack on Monday morning. A hacker, who called himself "The Messiah", threatened to expose her "hidden agenda" and release her personal data into the public domain, unless she "confess" to her "crimes".

The hacked website also made reference to the ongoing trial of six City Harvest leaders, including Kong, for allegedly misusing more than $50 million in church funds. The money is said to have been funnelled into sham bond investments to further the music career of Ms Ho and to cover up their tracks.

The site has since been taken down.
