Detained land rights activist Trinh Ba Tu informed his father, during a family visit, that on September 6, 2022 he began a hunger strike to protest against the ill-treatment he had reportedly been inflicted upon while in detention. He complained that he was placed in solitary confinement for ten days, during which he was severely beaten, foot shackled and denied access to the toilet, as a punishment for writing a complaint.

In May 2021, Trinh Ba Tu and his mother, Can Thi Theu, were both sentenced to eight years’ imprisonment followed by three years’ probation. In December 2021, his brother, Trinh Ba Phuong, was also sentenced to ten years imprisonment followed by five years’ probation.
