At 10:15 a.m. on 24 January 2013, six security agents appeared at the workplace of Mr. Le Anh Hung in Hung Yen and informed his boss that they needed to see him on issues concerning temporary residence papers. He was subsequently forced into a car and taken to an unknown location. His friends later found out that he had been interned in Social Support Centre No. 2 in Ung Hoa, Hanoi, a mental health institution. The director of the mental health institution prevented Mr. Le Anh Hung?s friends from visiting him and stipulated that he is being interned there upon request from his mother, which she has subsequently denied. It is reported that Mr. Le Anh Hung may be detained in Support Centre No. 2 under Ordinance 44 of 2002 on Handling of Administrative Violations, which allows for the detention of individuals without trial for up to two years under house arrest (probationary detention); in reformatories; educational institutions; rehabilitation centres or medical treatment establishments, including psychiatric wards. The provisions of the Ordinance relate to those who commit acts of violating legislation on security, public order and safety, but not to the extent of penal liability (Art 1.3 of Ordinance 44). On 1 February 2013, a Joint Urgent Appeal was filed by the Working Group on Arbitrary Detention; the Special Rapporteur on the promotion and protection of the right to freedom of opinion and expression; and the Special Rapporteur on the situation of human rights defenders. UPDATE 05/02/2013: Vietnamese blogger Le Anh Hung was released on February 5, 2013, about 12 days after he was arrested and held against his will in a psychiatric institution in Hanoi, the national capital, according to news reports. Hung was initially arrested on January 24 in the northern city of Hung Yen. Security agents said they needed to question him over his "temporary residence papers" but later detained him at Social Support Center No. 2, a mental health institution. The institution's director told Hung's colleagues that he had been admitted at the request of his mother and was not allowed to see visitors. The Observatory for the Protection of Human Rights Defenders, a coalition of three international rights groups, said in a public statement that Hung's mother had made no such request. Hung told Radio Free Asia after his release that he had been treated "normally" while held in the facility. He said he believed his detention was in connection with 71 critical blog posts he had written over the past five years about government corruption. The Observatory also reported that Hung had been subjected to repeated interrogations, threats, and harassment by police before his arrest. RFA reported that Hung had faced prior harassment for his online writings, which included critical blog entries on the abuse of power inside the ruling Communist Party.
