Hong Kong has announced its first arrests under a new security law - detaining six people for publishing social media posts which “incited hatred” against Beijing.

Five women and one man - including activist Chow Hang Tung - were arrested on Tuesday, it was announced.

Officials said the group were posting messages targeting a “sensitive date” - reported locally as the Tiananmen Square anniversary on 4 June.

If found guilty, the group could face up to seven years in prison under the harsher penalties brought in by the new law, known as Article 23.

The law, which was fast-tracked through Hong Kong’s pro-Beijing parliament in March, covers treason, sedition and state secrets, and allows for trials to be held behind closed doors.

It expands on the national security law, imposed by Beijing in 2020.
