Jakarta – A senior minister and the national police chief arrived in Indonesian Borneo Tuesday as calm returned after days of grisly ethnic violence that left over 200 dead and displaced more than 28,000 people.

Coordinating Minister for People's Welfare and Poverty Eradication, Haryono Suyono, and National Police Chief General Rusmanhadi arrived in West Kalimantan Tuesday, a provincial official said.

Suyono visited a refugee holding centre in the provincial capital Pontianak before leaving for the Sambas district where ethnic violence against Madurese settlers raged for nearly two weeks.

"General Rusmanhadi is in town to take part in a 'security safari' in Pontianak," an officer at the West Kalimantan police information office said in Pontianak.

The police chief, together with local officials, is to meet with ethnic group leaders there in a bid to defuse tensions in the city.

A fact finding team of 10 members of the national House of Representatives was also expected to arrive in Pontianak on Tuesday, information ministry official Solichin said.

"Thank God, the region is now calm and under control, we have not received reports of violence in the last three days," Solichin said.

An official at the refugee coordination centre in Pontianak said 28,227 Madurese settlers had been displaced by the violence and were being housed in holding centres.

Two members of the National Commission on Human Rights were Monday visiting Singkawang, the main town in the Sambas district, to meet with local leaders and seek out the root of the violence in an effort to prevent it flaring up again.

Pontianak police chief Lieutenant Colonel M. Daulay was quoted by the Kompas daily as saying that security authorities in West Kalimantan were taking no chances of violence breaking out in Pontianak.

"We will not take any risk. Whoever attempts to start an unrest will be hit," Daulay said. He said 12-member teams of soldiers and police would patrol 26 "critical spots" across the capital and surrounding areas and two armoured vehicles had been deployed in the city's north.
