The Hong Kong police National Security Department arrested two men in Cheung Sha Wan and Chai Wan on Saturday under the colonial-era sedition law.
The residences of the 31-year-old and 53-year-old were searched. “Some electronic communication devices which were used to publish seditious messages, a computer, military knives and an imitation firearm were seized,” a spokesperson said in a statement.
Police said the men were suspected of “doing an act or acts with seditious intention,” possession of an imitation firearm, an offensive weapon and the “possession of apparatus for radiocommunications without licence.”
The arrests come days before Chinese leader Xi Jinping is expected to swear in Chief Executive-elect John Lee amid high security and media restrictions.
Both men are being held by police.
