At 1.30 PM of May 11, police in the capital city of Hanoi violently suppressed a peaceful demonstration of around 20 drivers who protest the illegal collection of fee by the investor of the Thang Long- Noi Bai BOT (Build-Operate-Transfer) project. Police brutally beat male drivers including Lien Chan Pham, Dung Bui Tien, Bui Tien, Bui Trung and Nguyen Van and took them into custody, together with other female activists. Due to the police's brutality, many activists suffered severe injuries. Faces of many activists were covered with blood, said activist Nguyen Thi Thuy. A man named Hoa was bashed to the point that his mouth was bleeding, Thuy noted, adding police also towed away 11 cars belonging to activists. Videos provided by Tran Vu Tuan from Hanoi, well-known activist Nguyen Lan Thang, Hoa Nguyen showed several dozen members of law enforcement authorities, including riot police carrying truncheons, plainclothes police, the police (in yellow uniform), the army (in green uniform) reportedly positioned themselves at or on their way to BOT Thang Long " Noi Bai tollbooth " which is claimed by activists as a dirty tollbooth, ie it collects tolls illegally. Mr. Nguyen Lan Thang reported that the protestors were bashed. Thuy said police released five activists after five hours, and seven remaining after holding them one day in the temporary detention facility under the authority of the Soc Son district police. Police took Mr. Bui Tien to a remote area and released him after robbing his cell phone, said Thuy. His car was towed although he parked the vehicle far from the scence.
