North Korean defectors targeted by Chinese authorities in crackdown on ‘underground railroad’

“I heard voices, someone saying ‘shut up’ in Chinese,” said the woman, who spoke on condition of anonymity to protect her son’s safety. “Then the line was cut off, and I heard later he was caught.”
The woman, now living in South Korea, said she heard rumours her son is being held in a Chinese prison near the North Korean border, but has had no official news of his whereabouts.

It is not clear whether this is part of a larger crackdown by China, but activists say the raids have disrupted parts of the informal network of brokers, charities, and middlemen who have been dubbed the North Korean “underground railroad”.
“The crackdown is severe,” said Y.H. Kim, chairman of the North Korea Refugees Human Rights Association of Korea.
