12 Chinese labor activists have gone missing in the past few days- most of them students or recent university graduates. Following a demonstration in August, police stormed an apartment where some of these students lived and detained them. After this incident occurred, Cornell University ended ties with a university in Beijing which was complicit in punishing students involved in organized activity. Now, 12 of these students have been taken by authorities. Individuals who are close to these students believe authorities have abducted them in an attempt to silence the movement they have started.
