BEIJING (AP) — A Japanese newspaper says one of its Chinese employees has been detained by police ahead of the 25th anniversary of the 1989 crackdown on the Tiananmen Square pro-democracy protests.

Nikkei Shimbun said in a news report Tuesday the family of Xin Jian, a news assistant in its bureau in the southwestern city of Chongqing, was notified of her detention on suspicion of picking quarrels and provoking troubles.

Xin was taken away from her Chongqing home after police detained human rights lawyer Pu Zhiqiang, who attended a May 3 commemoration of the 1989 crackdown.

The ruling Communist Party tries to prevent commemorations or public discussion of the crackdown.

Nikkei said police initially told Xin’s family that police wanted her cooperation in Pu’s case.
