In a hand-written letter smuggled from the Immigration centre in the southern town of Padang Besar, the author talks of ''vulnerable women and children and physically weak men'' among the detainees.
The letter is headed: ''Appeal: The Thai government and humanitarian Thai people, world public opinion.''
The document came into the hands of a Phuketwan reporter yesterday in Thailand's south, where about 400 of the group have been held since March.
Although group spokespeople claim to have an affinity with Turkey and have support from the Turkish government, China says the group are members of its Uighur minority and wants them repatriated.
With the international arm-wrestle unresolved, the families at the centre of the dispute languish behind bars in southern Thailand. Thai officials grumble about the cost of supporting people who clearly do not wish to be in Thailand.
In the latest twist, some members of the group staged a two-day hunger strike in which the mothers also refused to allow their children to be fed.
After the 48-hour fast, seven women were banished from detention in Thailand's south to the province of Phang Nga, north of Phuket.
Two women said to be ring-leaders of the hunger strike were taken to Immigration detention in Phang Nga Town while five single women were to be held in a family shelter in Khao Lak.
The five women have since absconded, going over the wall at the low-security centre - and almost certainly into the hands of local Andaman coast people traffickers - after just two days. It's not known what the initial dispute was about.
The women fled with the arrival at the family shelter of several 17-year-old boys, youngest passengers among 134 boatpeople newly arrived from Bangladesh.
The men and boys were discovered in the hands of alleged human traffickers this week, near the town of Takuapa, not far from Khao Lak. With one exception, they told authorities they had been kidnapped.
The fate of those boatpeople is now being decided.
Although they all arrived in Thailand in the same boat from the same country, the likelihood is that Bangladeshi officials will take back their citizens but reject the stateless Rohingya refugees, even though they have been living in Bangladesh for as long as two decades and have families there.
Repatriations could happen quite quickly now that the international media has focused on the fate of the group, and human trafficking in Thailand.
The mysterious groups being held further south seem unlikely to be so fortunate.
Photographs taken yesterday in Padang Besar show young boys being held behind bars with their fathers, a decision that was accepted by Thai officials because the captive Muslim men insisted upon it.
North of Phuket, Christians, Muslims and Buddhists in the surrounding communities are equally insistent that arriving boatpeople be assessed to international standards to determine their future, not just quickly declared to be ''illegal immigrants'' and recycled into the hands of traffickers again.
Their community revolt against human trafficking is likely to win widespread support, especially with the expected arrival of record numbers of persecuted Rohingya from Burma's Rakhine state in Thailand during the ''safe'' sailing season between now and April.
While Thailand has clearly been stung into action by its mid-year demotion to Tier 3 in the US State Department's Trafficking in Persons report, most of that action has so far been cosmetic. Seminars don't save lives.
What the local activists are saying is that the coverup of the local cottage industry trade in people has to stop, and that Thailand needs to halt all trafficking - even if it has to do so alone, without help from Burma or its ineffective and disinterested Asean neighbors.
The plight of thousands of people said to be from China, from Bangladesh and from Burma will be filled with pain and suffering if Thailand fails to act while under international scrutiny.
