Greenfield Book Store, an independent bookstore in Mong Kok that has operated for about 50 years, says it will close when its lease expires. The shop made the announcement in social media posts in the early hours of Wednesday. The outlet in question is Greenfield Book Store on Sai Yeung Choi Street.\n\nSeveral reports link the closure to actions taken by Hong Kong national security police earlier this month. According to the accounts, national security police carried out a raid at or connected to the bookstore, and staff members were arrested around two weeks earlier. The reports describe the arrests and raid as being handled under Hong Kong’s national security framework.\n\nIn its statement about closing, the bookstore thanks customers for their support over the decades and indicates that it is not planning to extend its operations beyond the end of the lease. The sources do not provide further details in the cited coverage about charges or case developments tied to the arrests. The closure announcement centers on the impending lease end, while the coverage frames it in the context of the recent national security actions.
