HONG KONG - Hong Kong national security police arrested five people Wednesday in connection with two independent bookstores on suspicion of acts with seditious intent, heightening fears over the "unclear red lines" enforced on the city's freedom of publication.

The arrests of three women and two men, aged 30 to 59, were made after police raided the two shops -- Have A Nice Stay and Greenfield Book Store -- both located in the commercial district of Mong Kok, widely known for its prevalence of indie bookstores, according to local media reports.
