health facilities to contact the police regarding cases in which a woman was harmed physically, sexually, or psychologically in order to collect evidence and statements should the victim decide to prosecute. Sexual harassment is a criminal offense, punishable by up to two years in prison. The law encompasses sexual advances in the workplace or in educational institutions and between service providers or clients. In the workplace it applies only in hierarchical situations, where the harasser is of higher rank or position than the victim. Although the law was enforced, accusations were rare, and the extent of the problem was not documented. Prisoner violence The Brazilian prison system is considered insolvent for a long time. Prisons are overcrowded and unhealthy, and prison rape is not uncommon. There are over 400,000 inmates in the system. Beatings, torture and killings by prison guards occur throughout the system. Children are abused in the juvenile justice system. According to the Ministry of Justice, 13,489 teenagers are in detention. Prison overcrowding results in a prominent occurrence of prison violence and murder as well as frequent revolts and escapes. To deal with these problems, prison administrations often divide prison populations according to gang affiliation. According to Global Justice, there have been claims of gang affiliation being assigned. Living space, food, and human cleanliness conditions are inhumane and bribery for privileges and transfers is rampant. In December 2007, a case of prison gang rape in Pará brought media attention to the condition of human rights in the Brazil prison system. Other cases, like of the beating of two young suspects by two military police officers from the 4th Battalion in the city of Picos, Piauí, have also made the headlines. Prison conditions throughout the country often range from poor to extremely harsh and life-threatening. Abuse by prison guards, poor medical care, and severe overcrowding occurred at many facilities. Prison officials often resorted to brutal treatment of prisoners, including torture, harsh or dangerous working conditions, official negligence, poor sanitary conditions, abuse and mistreatment by guards, and a lack of medical care led to a number of deaths in prisons. Poor working conditions and low pay for prison guards encouraged widespread corruption. Prisoners who committed petty crimes were held with murderers. According to the National Penitentiary Department, in June there were 392,279 prisoners incarcerated, 40 percent more than the system's design capacity, and the number increased approximately 3,000 per month.
