Defend the Defenders: Authorities in the Mekong Delta province of Dong Thap have questioned the family of local prisoner of conscience Huynh Truong Ca about humanitarian supports it has been receiving from Vietnam's unregistered civil organizations and individuals in the country and abroad. On April 2, police in Hong Ngu district issued a summoning letter requesting Ca's daughter Huynh Thi Thai Ngan to be in the district police's headquarters on April 3 to answer police's questions regarding the financial supports his family has received from 50K Foundation, a charity foundation set up by Hanoi-based activist Nguyen Thuy Hanh. During the meeting, police officers threatened Ms. Ngan, saying she must not receive further supports from 50K Foundation and other sources. 50K Foundation was set up by Mrs. Hanh one year ago. Its beneficiaries mostly are prisoners of conscience and their families as well as activists-at-risk. Along with blocking economic activities of families of activists, authorities in their localities are striving to halt all support from other people in the country and abroad. In some case, plainclothes agents reportedly robbed families of activists when they went from banks after receiving supports.
