The most significant human rights problems included government restrictions on freedoms of speech and expression, press and media, assembly, and association. Of particular concern were police intimidation; sedition and illegal assembly investigations; charges against dozens of activists, lawyers, and opposition politicians; and the politically motivated prosecution and jailing of opposition leader Anwar Ibrahim. Restrictions on freedom of religion were also a significant concern--including bans on religious groups, restrictions on proselytizing, and prohibitions on the freedom to change one's religion.Other human rights problems included deaths during police apprehension and while in police custody; laws allowing detention without trial; caning as a form of punishment imposed by criminal and sharia courts; official corruption; violence and discrimination against women; discrimination against lesbian, gay, bisexual, transgender, and intersex (LGBTI) persons; and restrictions on the rights of migrants, including migrant workers, refugees, and victims of human trafficking. Longstanding government policies gave preference to ethnic Malays in many areas. The government restricted union and collective-bargaining activity, and government policies created vulnerabilities for child labor and forced labor problems, especially for migrant workers.The government arrested and prosecuted some officials engaged in corruption, malfeasance, and human rights abuses, although civil society groups alleged continued impunity.
