A student from Hong Kong who had been studying at a Japanese university has been indicted for ¡°seditious¡± online statements made while she was in Japan, a case that adds to fears over a sweeping national security law that is being deployed beyond the city¡¯s borders.

Yuen Ching-ting, 23, had returned from Tokyo in February to renew her identity card and was arrested in early March ¡ª a day before her scheduled flight to Japan ¡ª over her posts on social media, the South China Morning Post reported.

In the Thursday indictment, handed down by Hong Kong¡¯s National Security Department, she was charged with ¡°doing an act or acts with seditious intention¡± and accused by the prosecutor of using language that incites ¡°hatred or contempt¡± against the central government in Beijing and the authorities in Hong Kong, Nikkei Asia reported.
