It established that Yeo “did not manage [to] obtain and pass on any classified information about Singapore to his foreign handlers.”
“The threat that Yeo poses as a foreign agent is assessed to be effectively neutralized,” the ISD said.
“As such, he does not pose a security threat that warrants continued detention.”
Internal Security Act
The ISD arrested Yeo under the Internal Security Act (ISA) on Dec. 30, 2020, the day he arrived back in Singapore.In its statement announcing Yeo’s release, the ISD said its investigations had established that Yeo had knowingly and covertly worked for a foreign state to gather intelligence from 2016 to 2019.
Yeo was first approached through an online professional network site. Then he was invited to an overseas academic symposium where he was requested to write reports for his handlers.
He was paid “substantial amounts” for his reports, which were mainly on “global and regional geo-political issues and developments, including issues related to Singapore.”
Yeo sought “privileged information” on those issues and approached people he thought had access to such information. He also set up a company and placed employment advertisements online. When asked, he said the reports were “research topics” for foreign clients.
In addition, the ISD said: “On the direction of his handlers, Yeo had also applied for sensitive government positions in order to enrich his reports with privileged policy insights and classified information.
Recruiting Spies Through Social Media
In its statement, the ISD warned social media “has made it easier for foreign intelligence services to talent-spot, groom, and cultivate potential agents, even from abroad.”Likely targets are “retired/serving civil servants and individuals in the private sector with access to classified or sensitive information.”
“Singaporeans must therefore remain vigilant to such dangers posed by foreign agents,” the ISD said.
These agents may “offer attractive business or career opportunities, or even try to obtain sensitive information.”
The “foreign state” mentioned in the ISD’s press release was not named.
Yeo did not respond to The Epoch Times’s request for comments.
