Thailand's Narcotics Suppression Bureau (NSB) will seek the cooperation of the Malaysian authorities to interrogate a man they detained recently, for possible links with a Laotian, dubbed the 'ASEAN Drug Lord'.

According to NSB chief, Lt Gen Sommai Kongvisaisuk, the suspect who was picked up in Kelantan last Monday, was a dual holder of Malaysian and Thailand citizenship.

The Malaysian suspect had an arrest warrant for drug charges in Thailand under his Thai name, he told Bernama, adding that the arrest was made possible following information from the Thai authorities.

Sommai did not discount the possibility the NSB might request for the man's extradition to Thailand, but that the matter would be left to be determined by the Narcotics Control Board.

According to him, the authorities believed the Malaysian suspect headed a drug smuggling network in southern Thailand, which distributed drugs it received from the north and northeast part of the country.
