Uthayakumar was the former leader of Parti Reformasi Insan Malaysia (Prim), which broke off from
Parti Keadilan Nasional, which it accused of being anti-Indian, and was most recently the leader of the
Human Rights Party. As leader of Prim, Uthayakumar was involved in calling for an inquiry or formation of a royal commission to look into the
2001 Kampung Medan riots, an episode of sectarian violence between the Malay and Indian community. In 2004, Uthayakumar was threatened and assaulted at gunpoint by unidentified assailants. He applied for
asylum in the
United Kingdom and was placed in a safe house by the British government. He returned to Malaysia after the government publicly guaranteed his safety. in 2006, the
Hindu Rights Action Force (HINDRAF) was formed as a coalition more than 50 Hindu organisations in response to increasing
Islamisation and the ineffectiveness of the
Malaysian Indian Congress in advocating for the interests of
Malaysian Indians. In 2007, Uthayakumar participated in the HINDRAF-led
mass rally on 25 November against, broadly, racial and religious discrimination, with the ultimate goal of submitting a petition to the
British High Commission addressed to
Elizabeth II. This rally, participated by an upper estimate of 50,000 people, was preceded by a series of smaller rallies in previous months across the country. The police obtained a court order banning the rally and it was violently dispersed with the use of tear gas and chemical-laced water cannons. The rally and the government's response to it is understood to have contributed to its electoral setback in the
2008 Malaysian general election, where Malaysian Indian support for the government plummeted. ==Arrest and imprisonment==
