At least 60 detention camps are scattered throughout mountains along the Thai-Malaysian border, says a former president of the Rohingya Association of Thailand.
Thousands of Rohingya people who are possibly victims of human trafficking are being kept in the camps, reports the Bangkok Post.
"The discovery of the detention camp is just the tip of the iceberg. Currently there at least 60 detention camps along the Thai-Malaysian border," Bangkok Post quoted Abdul Kalam.
The Rohingya Association leader said about 150 to 800 refugees are being held in each camp.
Pol Gen Chakthip Chaichinda, deputy national police chief in Thailand, said he will meet investigators in Hat Yai district of Songkhla on Monday to verify the number of camps in the area.
"According to the information I have obtained there are many detention camps along the Thai-Malaysian border," Pol Gen Chakthip said.
Deputy government spokesman Sansern Kaewkamnerd said Prime Minister Prayut Chan-o-cha may consider using Section 44 of the interim charter to deal with human trafficking.
Thai police exhumed 26 bodies from a mass grave near a suspected human trafficking camp on a hillside deep in a southern Thai jungle on Friday and Saturday. All are believed to be migrants from Myanmar and Bangladesh. Authorities found three survivors at the camp, two of them children.
The discovery of the large camp, hidden deep in the jungle, came this week with the arrest of a trafficker named Anwar, who is thought to be one of southern Thailand's most significant traffickers.
