Hong Kong authorities arrested five people and seized materials from two independent bookstores in the Mong Kok district, marking the third round of such operations in four months following similar raids in March and June. Officers targeted Have a Nice Stay, a shop founded by former journalists, and the Greenfield Book Store, confiscating publications alleged to contain content stirring hatred against the city's government, judiciary, and law enforcement under Hong Kong's 2024 national security law. Security chief Chris Tang warned that booksellers bear responsibility for ensuring the titles they sell do not endanger national security, though authorities have declined to publish a list of prohibited books, saying enforcement will focus on content rather than titles.
