Hong Kong's largest pro-democracy paper Apple Daily has SLOTXO announced its closure, in a blow to media freedom in the city.
The tabloid's offices were raided last week over allegations that several reports had breached a controversial national security law.
Police detained the chief editor and five other executives, and company-linked assets were frozen.
The publication had become a leading critic of the Hong Kong and Chinese leadership.
The Apple Daily management said that "in view of staff members' safety", it had decided "to cease operation immediately after midnight" - making Thursday's publication the final printed edition.
The Hong Kong Free Press website reports that a million copies of Apple Daily will be printed on Thursday.
UK Foreign Secretary Dominic Raab said the paper's closure was a "chilling blow to freedom of expression in Hong Kong".
The digital version of the 26-year old paper will no longer be updated after midnight.
