Hong Kong independent online publication Citizen News said on Monday its decision to shut down was triggered by the closure of a pro-democracy media outlet last week following a police raid and seven arrests. Stand News, a prominent pro-democracy news site, closed last week after 200 police officers raided its newsroom, froze its assets and arrested seven people on suspicion of conspiring to publish seditious material. Citizen News said on Sunday it will cease operations from Tuesday, describing the media environment in the Chinese-ruled city as “deteriorating,” and citing the need to ensure the safety of its staff.
