Bangladesh police have stopped 43 Rohingya refugees from being smuggled to Malaysia by boat, with a dozen women claiming they were abducted by traffickers, officials said on Thursday.

Acting on tip-offs, police found the refugees at two separate places in the southeastern border district of Cox’s Bazar, raising the number of Rohingya being rescued from the traffickers to more than 100 in less than a week.

About 740,000 of the Muslim minority fled Myanmar for Bangladesh after a military clampdown in the Buddhist-majority nation in August 2017.

They have joined another 300,000 Rohingya who have already been living in overcrowded camps in Cox’s Bazar following previous bouts of violence.

Officials fear many may end up being exploited by an internationally organised human smuggling racket which has previously sent thousands of Rohingya to Malaysia by boats until Bangladesh launched a crackdown in 2015 following the discovery of mass graves of refugees in Thailand.

Rapid Action Battalion, an elite police unit, said they rescued 12 women – mostly in their 20s – from a residential room in Cox’s Bazar city early Thursday morning and arrested two alleged traffickers for “abducting” them.

“The young women from the refugee camps were lured by the traffickers. They were promised they would be sent to Malaysia. They were then brought to Cox’s Bazar and kept in a house,” RAB spokesman Mashkur Rahman said.

Rahman said they were treating it as a case of abduction after the women claimed they were confined in a room without consent.

In another drive late Wednesday, Cox’s Bazar police rescued another 31 Rohingya from the southern island of Maheshkhali, some 110 kilometres (70 miles) away from the overcrowded Kutupalong refugee camp.

Local police chief Provash Chandra said the 14 women, 11 men and six children were hiding in a coastal forest at Maheskhali waiting to board a Malaysian-bound boat.

“They paid some 20,000 taka ($240) each to the traffickers for the journey,” he said.

He said they arrested a woman trafficker and were “searching for others.”
