The police have confirmed that the Infocomm Development Authority (IDA) has filed a report about a threat to leak public officers' personal information. Responding to queries from The Straits Times on Saturday, a police spokesman said that they are "looking into the matter".

Tech-news website ZDNet reported on Friday evening that it had received a statement containing personal information, including the names, government e-mail addresses, birth dates, nationalities, and passport and mobile phone numbers of 10 individuals, from someone claiming to be from the hacktivist group, Anonymous.

Anonymous reportedly indicated that the information in its possession was just the tip of a list with the personal information of "thousands of people associated with a certain Singaporean security corporation that does much business with the government".

The group said it would publicise the information over the next day, and the ZDNet report said in an update on Saturday morning, that the statement by Anonymous had been made public online.

The IDA said on Friday night that it was investigating the threat, and had alerted the police. When the tech-news site conducted a check, however, it reportedly found some of the data in the statement to be incorrect, with phone numbers and email addresses out of date.

'Anonymous' reportedly took issue with the arrest of 35-year-old James Raj Arokiasamy, the alleged hacker behind the pseudonym "The Messiah" who faces one charge of hacking into the Ang Mo Kio Town Council website on Oct 28.

James Raj is due to appear in court for a pre-trial conference on Monday. It also took issue with the arrests of 17-year-old Melvin Teo and Delson Moo, 42, who allegedly hacked into and defaced the Istana website.
