BUKIT WANG BURMA, Malaysia (Reuters) - Malaysian police forensic teams, digging with hoes and shovels, began pulling out the remains of dozens of suspected victims of human traffickers on Tuesday from shallow graves discovered at a jungle camp near the border with Thailand.
On Tuesday, the authorities took a group of journalists to one of the camps, nestled in a gully in thick jungle up a steep, well-worn path about an hour's walk from the nearest road. Apparently abandoned in haste, what remained of the camp was little more than a tangle of bamboo and tarpaulin, but one police official, who did not want to be identified, said it could have held up to 400 people.
The first body was removed on Tuesday afternoon, a Reuters witness said. Muhammad Bahar, of Perlis state police CID, said he could not confirm the state of the body or how long it had been there, but added the grave could contain more bodies.
Malaysian authorities said on Monday they had found 139 graves, some containing more than one body, around 28 camps scattered along a 50km stretch of the border in the northern state of Perlis.
The government said it was investigating whether local forestry officials were involved with the people-smuggling gangs believed responsible for nearly 140 such graves discovered around grim camps in the country's north-west.
The dense forests of southern Thailand and northern Malaysia have been a major stop-off point for smugglers bringing people to South-east Asia by boat from Myanmar, most of them Rohingya Muslims who say they are fleeing persecution, and Bangladesh.
The grisly discoveries in Malaysia followed the uncovering of similar graves on the Thai side of the border at the beginning of May, which helped trigger a regional crisis. The find led to a crackdown on the camps by Thai authorities, after which traffickers abandoned thousands of migrants in overloaded boats in the Bay of Bengal and Andaman Sea.
"We don't know if there is a link between the Thai camps and Malaysia camps," Mr Phuttichart Ekachan, deputy chief of Thailand's Provincial Police Region 9, told Reuters. "It is possible that because of the Thai crackdown some of the camps moved and some of them (migrants) then walked over or escaped to the Thai side. It is possible but it isn't something we have been able to confirm."
Thousands of Rohingya Muslims are ferried by traffickers through southern Thailand each year, and in recent years it has been common for them to be held in remote camps along the border with Malaysia until a ransom is paid for their freedom.
State news agency Bernama quoted Malaysia's police chief, Inspector General of Police Khalid Abu Bakar, as saying that the camps were thought to have been occupied since 2013, and two were "only abandoned between two and three weeks ago".
Insp-Gen Khalid told reporters on Monday that police had been"shocked by the cruelty" of the fenced camps, where he said there were signs of torture.
The scale of the discoveries has raised questions about the level of complicity by officials on both sides of the border.
Malaysia's Home Minister Ahmad Zahid Hamidi said on Tuesday that initial investigations revealed links between forest rangers and smuggling syndicates, Bernama reported, adding that some had been detained by police as part of the probe.
"We suspect some of them were involved... but we are working with the forestry department in terms of enforcement as they are supposed to carry out enforcement in the area," he was quoted as telling reporters at Parliament.
A large plastic water tank could be seen at the camp visited by Reuters reporters on Tuesday, suggesting a degree of permanence. A call to Muslim prayers could be heard drifting from a nearby settlement.
An official said 37 graves had been found at the site, a few hundred metres for the Thai border. As the police teams began to dig, a large supply of body bags and white cotton shrouds was piled on the ground.
On Monday evening, the police had removed a badly decomposed body found unburied in a shack at one of the camps. Police said the unidentified person had been dead around two or three weeks. "The victim could have died and the syndicate did not have time to bury the body as they were rushing to leave the camp," Bernama quoted local district police chief Rizani Che Ismail as saying.
Residents in the town of Wang Kelian, on the Malaysian side of the border, said they were used to seeing migrants in the area.
"They are often starving, not eaten for weeks," said Mr Abdul Rahman Mahmud, a resident who runs a small hostel. "They eat seeds or leaves or whatever they can find. It's a real pity and it's sad to see this."
