UPDATE: Guangzhou police have refused to provide the family members of #HuangXueqin and #WangJianbing with detention notices and they have refused to clarify the criminal charges they are being detained on.
Wang Jianbing's family has gone to four places (广州市海珠区新港派出所、海珠区公安分局、广州市公安局、广东省公安厅等四级部门进行信访) in Guangzhou seeking written detention notices and to know the criminal coercive measures they are detained on.
But they've been refused.
However, the Haizhu District Police Petitioning Office Chief said Wang Jianbing's case is being handled by the Guangzhou Police, but the crimes and measures taken, we can't tell you.
“王建兵案的办案单位是广州市公安局,涉嫌罪名和采取具体强制措施的情况不便告知。”
He added:
"The case is underway, you don't need to go looking everywhere. In some special cases, [we] can't just notify the family members right away."
On Sept. 30, Wang's family got a call from the Chigang police station, telling them to come to a meeting.
There, 3 unidentified men said: He's been detained by the GZ police. Can't say measures. Can't say the crime. Don't go looking for him and stay silent about the case too.
