Hong Kong police question 2 polling institute workers in national security probe

National security police have summoned two employees of a polling organisation, who used to work under a Hong Kong fugitive, to help with an investigation, after questioning his family members and a leading pollster.

A source said on Thursday that the two staff members at the Hong Kong Public Opinion Research Institute were asked to assist in the investigation linked to Chung Kim-wah, a former deputy executive director of the institute and an outspoken commentator.

Stanley Chu, the organisation’s research and data science manager, was questioned at the Castle Peak police station in Tuen Mun, while research executive Adam Yuen headed to the Sha Tin police station.

Police confiscated items from the Hong Kong Public Opinion Research Institute’s office last week and escorted its president, Robert Chung Ting-yiu, from his home as part of the investigation.

The force also interrogated Chung’s three younger siblings on Wednesday, and his wife and son last week.

Chung, who moved to Britain in 2022, was among six wanted overseas-based activists named by police last month for allegedly contravening the national security law.
