Hoang Duc Binh reported to his family that he was put in leg shackles for 10 days, from March 26 to April 5, by warden Nguyen Ngoc Thach at An Diem Prison in Quang Nam Province. He also has been prohibited from receiving supplies or calls from his family for three months, as well as family visits for two months. According to Binh’s family, Binh was punished for protesting against unfair treatment by the warden, who did not let him have several items sent by his family and cited him for “not following orders by prison authorities.” While Binh was in shackles, guards allegedly confiscated his personal belongings, as well as those of other political prisoners. At least four political prisoners went on a hunger strike to protest the mistreatment: Hoang Duc Binh, Trinh Ba Phuong, Phan Cong Hai and Nguyen Thai Binh. As a result, all four were put in “disciplinary cells” and were not allowed to go out to the yard or communicate with other inmates.

In a letter home dated April 8, Trinh Ba Phuong corroborated Hoang Duc Binh’s account of being disciplined and the group’s hunger strike. Phuong’s wife, Do Thi Thu, was able to visit him on April 21 and reported that Phuong and several other political prisoners had been locked in their cells since April 8 with everything passed in and out through a small opening. Phuong told Thu it was a form of psychological torture. Phuong also said that Binh is suffering from back pain, abdominal pain, loss of smell, and chest pain. Binh did ask prison authorities for medication for his chest pain but so far has reportedly not received any. Thu also reported that for the past year, Phuong has not been eating any food made by the prison; at one point, the food caused him severe diarrhea and stomach problems. Phuong also said the water source at An Diem is highly polluted.
