North Korea Reportedly Has Secret Prison at Their Embassy in Beijing
This should not be surprising to anyone. I would be more surprised if they didn’t have their own prison at their Beijing embassy to hold defectors in:

North Korea allegedly runs a secret detention facility in its embassy in China to interrogate and repatriate its nationals deemed threats to the regime, a report said Tuesday.
The claim was made in a report titled “North Korea’s Transnational Repression: China” released Tuesday by the Transitional Justice Working Group (TJWG), a Seoul-based human rights group.
Based on interviews with multiple sources, including a former North Korean diplomat, the report claimed North Korea operates the facility in the basement of its embassy in Beijing, where surveillance, pursuit and arrest, detention and interrogation, and forced repatriation take place.
The secret operation is overseen by a “security representative” who holds a consular post but is reportedly a North Korean intelligence agency officer on a temporary assignment. Cases are reported to Pyongyang within 12-24 hours, according to the report.
