SINGAPORE: The police have arrested another six people in relation to a series of unauthorised attempts to change registered residential addresses through an online service provided by the Immigration & Checkpoints Authority (ICA).Â
This brings the total number of arrests made so far to 13.
The latest suspects - five men and one woman aged between 17 and 38 - were nabbed following islandwide operations, the police said on Friday (Jan 17).
Police had arrested seven people - six men and one woman aged between 19 and 32 - in similar operations between Jan 11 and Jan 13.Â
In total, the 13 suspects are believed to be responsible for at least 66 cases of attempted unauthorised address changes.
Nine of them are being investigated for alleged offences under the Computer Misuse Act. Another two are being investigated under the same act for unlawfully disclosing access codes.
One suspect is being investigated for transmitting the Singpass credentials of another person, while another is under probe for allegedly transferring benefits from criminal conduct.
Some of the suspects are also being investigated by ICA for alleged breaches of national registration regulations.
Of the 13 suspects, four of them, aged between 26 and 38, have been charged so far.Â
Three people - all Singaporeans - appeared in court on Friday morning and according to the prosecutor, their alleged offences are believed to be syndicated.
Ng Wei Chang, Yuen Mun Fei and Koh Hong Yan have all been charged over unauthorised attempts to change residential addresses on ICA's service, while a 31-year-old man was also charged on Wednesday over the unauthorised disclosure of access codes under the Computer Misuse Act.
He is accused of abetting the disclosure of the PIN from ICA, to facilitate the unauthorised change of a victim's address.Â
The arrests come after ICA revealed on Jan 11 that perpetrators were exploiting stolen or compromised Singpass accounts to fraudulently alter the addresses of unsuspecting victims.
ICA's investigations began in September last year after receiving reports from members of the public who encountered unauthorised changes to their residential addresses.
By last December, it found that the perpetrators had used stolen or compromised Singpass accounts to change the residential addresses of the victims through the "Others" option - which allows the change of address by a proxy.
The police said that following the discovery of the series of unauthorised attempts to change registered residential addresses, they visited the addresses of those affected.
"Four out of 32 valid addresses to where PIN mailers were sent were found to have unsecured or faulty letterboxes, and this would have enabled the perpetrators to easily get the PIN mailers," the police noted, adding that the victims were advised to secure their mailboxes.
Members of the public are advised to check their registered address on ICA's website to ensure it is correct and to report any inaccuracy via FormSG.

Investigations are still ongoing and the police said on Friday they will spare no effort to track down further suspects.
The offences under the Computer Misuse Act carry jail sentences of up to three years, fines of up to S$10,000, or both.
Editor's note: The age range of the six suspects has been amended following an update from the police.
