A total of 123 illegal Bangladeshi migrants have been found on Khao Kaew mountain in adjacent areas of Hat Yai and Rattaphum districts of Songkhla, Thailand.
Local police spotted 32 more migrants, all males, walking along the edge of a forest in tambon Tha Chamuang in Rattaphum on Saturday, a day after 91 Bangladeshis along with 117 trafficked men were rescued from the same area.
Later, the 32 men were taken to Ban Khlong School in the district before being sent to a temporary shelter at the Rattaphum district office, where the 117 illegal migrants have been given refuge, reported Bangkok Post.
Of the suspected trafficking victims, 26 are Rohingya Muslims from Myanmar, Reuters quoted Ekarat Sisen, deputy governor of Songkhla Province.
Thai authorities on Saturday interrogated the 117 rescued migrants to determine whether they were victims of human trafficking.
Ekarat Sisen said: "We need to figure out if any these people are trafficking victims or whether they entered country on their own. If they are victims of human trafficking we must hand them over to Ministry of Social Development and Human Security.
"Those who voluntarily entered the country illegally will be sent immigration police and eventually sent back to their country of origin."
Police had said on Friday that 111 migrants were found.
