Former prisoner of conscience, Nguyễn Bắc Truyển was last seen on 30 July 2017 after dropping off his wife outside her place of work in Ho Chi Minh City, Viet Nam. Although State media reported that he was arrested by authorities, more than three weeks later his wife has received no official confirmation from police as to the accusations against him or his place of detention. He is at risk of torture or other ill-treatment and has pre-existing medical conditions that require treatment.
