The two men, suspected of plotting terrorist attacks in Thailand, fled the country at the end of March.

Immigration director-general Sakib Kusmi said they would have been detected if they had entered Malaysia through border checkpoints, but there were no traces so far.

“However, if the two men came in through an ungazetted route, it would require the cooperation of the relevant security agencies to detect their presence,” he said today.

The Governor of Surat Thani in southern Thailand, Wongsiri Promchana, told Bernama yesterday that information from the Phuket Immigration Office showed that the two men were believed to be heading to Malaysia.

The Inspector-General of Police, Khalid Abu Bakar, said police had yet to receive information about the two men entering the country through a legal route.

Hence, he said the police had intensified surveillance on illegal routes at national borders.

At the end of last year, two ethnic Uighurs of Chinese nationality were detained, after being involved with the bombing incident at a temple in Thailand’s capital, which killed 20 people.
