Hong Kong authorities have raided two bookstores and arrested five people on suspicion of selling allegedly seditious publications, in the latest step targeting independent booksellers.

Videos and photos from multiple media outlets on Wednesday showed officers wearing vests marked with “police” seizing boxes from the building that houses Have A Nice Stay, a bookshop founded by former journalists. AFP reporters saw officers also lead away a woman in handcuffs to a van.

The Have a Nice Stay bookstore had already announced it would shut down on 30 August. In a social media post, it said financial difficulties and an elusive red line were among the factors.
