A total of 112 people, including a dozen children, were arrested in the southeastern township of Bogale, according to the Global New Light of Myanmar, with 35 given five-year prison terms.

The report, which identified the group by the pejorative "Bengalis", gave no date for the arrests, but local media quoted police sources as saying they took place the morning of December 20.

Widely viewed as interlopers from Bangladesh, members of the mostly Muslim minority group are denied citizenship – along with access to healthcare and education – and often require permission to travel.

A local court sentenced 35 of the group to five years in jail for traveling without documents, the Global New Light reported, adding that 13 under the age of 18 would be detained at a "training school" until they were 20.

Thirteen Rohingya were found dead on a roadside near Hlegu town near the commercial hub Yangon on December 5. 

Myanmar police later arrested 12 suspected members of a human-trafficking gang linked to the deaths.

A Rohingya source and local media said the group had been traveling inside an oil tanker linked to the gang.
