"There is no report of any warrant issued for the arrest of Duminda Silva or any others"

The United National Party (UNP) accused the government of not doing enough to investigate the incident despite two government advisors have used the firearms provided by the government to shoot at each other.

Presidential advisor on trade unions Bharatha Lakshman Premachandra and two others were shot dead allegedly by the supporters of Duminda Silva, MP, on Saturday.

Mr Silva, an adviser to Defence Secretary Gotabhaya Rajapaksa and a close associate of President Rajapaksa's eldest son, Namal, MP, is still in intensive care unit after a brain surgery.

'Guns hold sway'

"This gives a very bad precedent for the country because we accuse the government of not taking any action against this," Tissa Attanayake, the UNP general secretary, said journalists in Colombo.

The Asian Human Rights Commission (AHRC) says police have even failed to file a report on the incident before a magistrate's court according to the criminal procedure code, let alone to arrest any suspects.

"There%20is%20no%20report%20of%20any%20warrant%20issued%20for%20the%20arrest%20of%20Duminda%20Silva%20or%20any%20others%20regarding%20the%20triple%20murder," the AHRC said in a statement.

Police spokesman, SSP Maxi Proctor, admitted that no arrest has so far been made related to the shooting incident on the polling day.

Rejecting any political pressure against arresting the suspects, he insisted that the Criminal Investigation Department will conduct a proper investigation.

The AHRC says the incident is a clear indication of the violent politics prevailing in the country.

The violence underlines the fact that, although the government regularly says it defeated terrorism with its war victory, much politics here is underpinned by violence, and government politicians with guns hold sway in various parts of the country, says the BBC's Charles Haviland in Colombo.
