The morning of 21 October 2011, pro-democracy activist, Cao Haibo was arrested by the Kunming Public Security Bureau on charges of “incitement to subvert state power.” Reports say his arrest was sudden, carried out by four plainclothes police officers who failed to show any formal documents for his arrest and who also prohibited him from notifying anyone. A few days thereafter, police officers raided his home, taking with them three telephones, a computer, a USB stick, and two bank cards among other things.
