The four men did not arrive in Thailand in the October time ''window'' mentioned in the Russian document saying that 10 potential terrorists had entered Thailand and were spreading out to Bangkok, Pattaya, Phuket and other places.
However, Immigration may be keen to locate the four Syrians, even if only to charge them with overstaying their visas.
.. Abul Aziz Rouk, 44, entered through Ranong on Jaanuary 27, visa expired April 26.
.. Mouayad Hanati, 29, entered through Suvarnabhumi Airport, July 7, visa expired October 4.
.. Hagop Kassabian, 57 , entered through Suvarnabhumi Airport May 16, visa expired August 13.
.. Nawfal Hassoun, 34, entered overland from Laos, August 3, visa expired October 31.
Immigration police chief Pol Lt Gen Nattatorn Prohsunthorn said the number of Syrians visiting Thailand was very small.
''In mid-October, 200 of them came here but most of them have already left. There are now no more than 20 here at present.
''It's not yet known whether the 10 people in the warning are among the 200,'' he said.
