The five men are leaders of the non-governmental Hindu Rights Action Force (Hindraf), which had spearheaded a mass protest in November last year against the alleged marginalisation of ethnic Indians in this country.

The rally, which was declared illegal by the government, was attended by over 20,000 ethnic Indians.

The detainees will begin their fast in jail on Sunday and will drink only water for at least five days, lawyer N Surendran, who is representing one of the five men said on Friday.

He said that their detention is illegal and claim that the government took them into custody for politically motivated reasons.

The activists, who were detained last month under the Internal Security Act, are accused of threatening public security and inciting racial hatred in this multi-racial nation.

Malaysia’s population of 27 million people comprises majority Malays who are all Muslims, 25 percent ethnic Chinese who are Buddhists and Christians, 7.8 per cent Indians who are mostly Hindus with origin from Tamil Nadu.
