BEIJING (AP) — Chinese authorities say they have formally arrested a rights lawyer who is well known for his efforts to defend free speech, abolish labor camps and publicize abuses by police and Communist Party officials.

Beijing’s Public Security Bureau said on its microblog website that attorney Pu Zhiqiang was arrested Friday on suspicion of “creating a disturbance” and “illegally obtaining personal information.” It did not provide details.

Investigations into other alleged crimes were ongoing, an indication that Pu could eventually face more charges.
