A 50-year-old independent bookstore in Hong Kong has announced it will close when its lease ends, following a raid by national security police. Greenfield Book Store, located on Sai Yeung Choi Street in Mong Kok, posted on social media early Wednesday that it would shut down, thanking customers for decades of support. The announcement came after police searched the shop earlier this month. According to Japan Times, authorities raided two bookstores and arrested five people on suspicion of displaying and selling items with seditious intent. The bookstore's closure marks the end of a half-century presence in the city's bustling shopping district. The police operation is part of broader enforcement under Hong Kong's national security law, which has been used to target perceived threats to state stability since its imposition in 2020. Neither the bookstore nor authorities have provided further details on the specific items seized or the charges against those arrested.
