A Christian and Labour rights activist has been arrested in China for more than a year.

Li Qiaochu, according to her supporters, has been wrongly charged of inciting subversion and worries that she is being mistreated while in detention.

In the eastern providence of Shandong, the People's Procuratorate of Linyi City, filed the indictment before the Intermediate People's Court on Feb 28.

Li was accused by them of working to overthrow China's socialist system and charged her with inciting subversion of state power, a charge punishable by up to 15 years in prison.

Teresa Zhao, a close friend of Li, rejects the charges and said she was prosecuted because of her relationship with her boyfriend  Dr. Xu Zhiyong, who is also currently in prison.

"Li would never have done anything illegal to incite the subversion of state power, I and her other friends call for a fair and objective trial.

"We are particularly worried about her physical and mental health, and if she is being abused in detention. 

"We hope that she can be released on medical parole as her family has requested many times." 

Li was born in 1991, a native of Beijing, was a former research assistant at the School of Labour and Human Resources of Tsinghua University, a labour rights advocate, a Christian, and a protester who regards "revolution and love" as the theme of her life.
