Hong Kong police
on Sunday detained 47 pro-democracy activists on charges of conspiracy to commit subversion under the city's
national security law
and democracy advocates had been previously arrested in a
sweeping police operation
in January but were released. They have been detained again and will appear in court on Monday, police said in a statement.
They allegedly violated the new national security law that was imposed by Beijing for participating in unofficial election primaries for the semi-autonomous Chinese territory's legislature last year.
The defendants include 39 men and eight women aged between 23 and 64, police said.
The pro-democracy camp had held the primaries to determine the best candidates to field to win a majority in the legislature and had plans to vote down major bills that would eventually force Hong Kong leader
In January, 55 activists and former lawmakers were arrested in a police operation for their roles in the primaries. The arrests were seen as the biggest move against Hong Kong's democracy movement since Beijing imposed the national security law last June to quell dissent following months of anti-government protests in 2019.
Authorities said that the activists' participation was part of a plan to paralyse the city's legislature and subvert state power.
Among those arrested on Sunday was former lawmaker Eddie Chu. A post on his official Twitter account confirmed that he was being charged for conspiracy to commit subversion and that his bail was denied.
Another candidate in the primaries, Winnie Yu, was also charged and will appear in court on Monday, according to a post on her official Facebook page.
