Thai police have arrested two Myanmar workers they say confessed to killing a pair of British tourists on a beach in southern Thailand last month.

Thailand's national police chief Gen. Somyot Poompanmoung said Friday that the two suspects face charges of murder, rape and theft in the attack on Koh Tao, an island known for its pristine diving sites.

He said that DNA results, closed-circuit television footage and other evidence have backed up the men's confessions that they raped and killed Hannah Witheridge, 23, and murdered David Miller, 24.

The men were brought to the murder scene Friday as part of the investigation amid tightened security.

The Friday arrests came after weeks of pressure on police to solve a case that has threatened to damage the country's tourism industry.
