E/CN.4/1995/34 page 17 67. Manoel Delfino Felix da Silva, Osvaldo Duarte da Silva, and Valdemir Alves da Silva were among five lavradores detained on 23 and 24 January 1994 by military and civil police officers from Couto Magalhaes, Tocantins State, in connection with the killing of a local councillor in a conflict over land tenure. They were taken to Couto Magalhaes police station where they were allegedly beaten and severely bruised. Valdemir Alves da Silva was also said to have been taken to a nearby stream where his head was submerged in water until he nearly drowned. Manoel Delfino Felix da Silva was taken to hospital, where a doctor reportedly diagnosed his bruises to be consistent with heavy blows to his upper body. 68. Josemar Cantuario de Oliveira was detained on 26 January 1994 in Coneiçao do Araguaia, Pará State, by members of the civil police on the same grounds as the aforementioned persons. He was allegedly severely beaten and subjected to other forms of torture at the Guarai police station in Tocantins. He was also said to have been denied proper medical attention for a bullet wound to his leg. 69. Antônio Ferreira Braga was reportedly tortured on 12 April 1993 in the police station in Fortaleza, Ceará State. He was allegedly partially asphyxiated by having the rubber inner tube of a car tyre placed over his face and was also beaten with a wooden baton while wrapped in a roll of carpet to prevent exterior bruising. A local Bar Association commission of inquiry was said to have discovered the torture and to have come across a stock of torture instruments while visiting the police station. 70. The Special Rapporteur also advised the Government that he had received information according to which street children and educators working to assist such children had been the targets of street violence in São Paulo. On 12 December 1993, educators Jonathan Luke Hannay and Jonas Beltrão de Oliveira were trying to mediate in a confrontation between children and military police. A police officer allegedly hit Rosângela, a 16-year-old girl, over the head with a gun and another officer allegedly hit Jonathan Hannay in the stomach with a piece of wood. Some of the street traders in the area then reportedly began to beat Jonas Beltrão on the neck with a piece of wood. When he asked the police for help, the officer in command allegedly responded that he would do "nothing" and ordered his men out of the square. The two educators were then punched, kicked and beaten by members of the crowd before the police eventually told the crowd to disperse. Jonas Beltrão was said to be semi-conscious with blood coming out of his ear and a large wound on the back of his neck. He received emergency treatment for a concussion and a perforated eardrum.
