The police have arrested a 64-year-old man for allegedly using social media to incite others to target government officials and judicial officers.
The force said on Tuesday the suspect allegedly told someone who had expressed suicidal thoughts on social media to kill government officials and judicial officers as well in a post.
Authorities said they later located the suicidal person who was not in any danger.
The suspect, who's a hawker, was arrested in Fanling on Monday.
Chief inspector Cheng Chak-yan from the Cyber Security and Technology Crime Bureau said no names were mentioned in the post.
"Though he did not specifically mention any government officials or judicial officers, we are not simply focusing on a particular post but we will view the whole context of the Facebook account or Facebook page, to collect evidence to establish the requisite intention to constitute the incitement offence," he said.
