Hundreds of Vietnamese protestors have been arrested and beaten by security forces in recent days and the numbers would rise as the local authorities continue their crackdown on the local dissent, according to the state media and citizen journalists. State media has reported that security forces had arrested around 200 protestors in the central province of Binh Thuan, where the peaceful demonstrations turned into violent after the local security forces used tear gas and water cannon to disperse the crowds. The Vietnamese government was said to deployed special police units from the capital city to Phan Thiet town and Phan Ri commune in Binh Thuan to suppress local rioters after the local police units surrendered under the pressure of the local citizens. According to a local resident, police used batons to beat local residents on their faces and heads. Two residents were reported to die after being assaulted by police. From June 10, security forces in Ho Chi Minh have arrested hundreds of protestors who are local citizens and people coming from other southern provinces and cities. No one knows the exact number of the detainees because many of them came from other localtions, said Facebooker Hoang Dung with nickname of Dung Hoc-gia, adding around 150 protestors have been held in Phan Dang Luu temporary detention facility under the authority of the HCM City Police Department. There are many other facilities holding the protestors arrested in recent days, other activists said. Activist Nguyen Dang Vu (Facebooker Nguyen Peng) is likely one of the latest victims of the government's crackdown on peaceful demonstrations protesting the two bills on Special Economic Zones and Cyber Security, the first was postponed while the second was approved by the Vietnamese rubber-stamped parliament on June 12. On the afternoon of Tuesday, he went on Hoang Van Thu street in HCM City for taking pictures and later informed his fellows that he was caught by police. Being released on the late afternoon of June 13, the activists said there are many protestors held in different facilities in the city. The fates of many protestors are unknown for their families. Some were released, others deported to their localities, while hundreds of the remaining were held somewhere in the city. The released protestors reported that in custody, police had brutally beaten detainees and confiscated their cellphones and other belongings during interrogation. Witnesses said authorities in HCM City, Hanoi, Danang and Nha Trang sent armed police to block demonstrations and used plainclothes to detain protestors. Many videoclips proved their claims. Video clips showed that the police in HCM City used Long Range Acoustic Devices (LRADs) to suppress peaceful demonstrations on Sunday. The devices were imported from the US for equiping patrol ships of the Vietnam Coast Guard. On Sunday, police in Hanoi also dispersed peaceful demonstrations in the city's center. Police detained protestors, holding in police stations and releasing them in late afternoon. Police brutally beat Mrs. Nguyen Thuy Hanh when she stayed with her fellows in a cafeteria in Dong Da district, after conducting a rally with their motorbikes. She was released at the mid night of Sunday, with the deformed face and many injuries at her head and body. She said a police officer from Dong Da district police beat her with his fists in a taxi car from the cafeteria to the Trung Tu ward police station and in the station where they held her and seven other activists. Authorities in Hanoi sent plainclothes agents and militia to private residences of local activists at noon of June 12, after the parliament approved the bill on Cyber Security, in a bid to prevent them from gathering to protest. Some activists said they are still placed de facto under house or being closely followed by under-covered police on Wednesday.
