A Hong Kong man was jailed Friday for "seditious" posts on social media, becoming the third person to be imprisoned under a new national security law in the span of two days.

Chu pleaded guilty plea to having seditiously worn a T-shirt with the protest slogan "Liberate Hong Kong, revolution of our times". The message - chanted on streets during the months of pro-democracy protests that rocked Hong Kong in 2019 - had been deemed capable of inciting secession in a separate national security case.
