HONG KONG: Hong Kong’s security chief said on Thursday that booksellers must ensure the items they sell “do not endanger national security,” a day after authorities arrested five over “seditious” material. National security police searched two bookshops on Wednesday and arrested five people under suspicion of displaying and selling “items with seditious intent,” the latest in a string of crackdowns on independent bookshops. AFP reporters saw officers lead a woman in handcuffs to a van and taking away several boxes from Have a Nice Stay, a bookshop run by former journalists.

Hong Kong was once known for its freedom of publication, but political changes have created a challenging environment for independent bookstores.
