KUALA LUMPUR - Three Rohingya migrants were detained to assist investigations into the mass graves uncovered in Wang Kelian, Perlis.
Inspector-General of Police Tan Sri Khalid Abu Bakar said the migrants were arrested in Johor Baru three days ago.
"We believe the trio were among those who were at the camp (in Wang Kelian) but we have not confirmed it.
"We will gather more information. Give us some time as we are interviewing them," he told a press conference in Bukit Aman on Tuesday.
He added initial investigations revealed that the trio were victims rather than part of the human smuggling syndicate responsible for the mass graves.
"We want to know what happened at the camps. Maybe these three will shed more light into it," he said, adding that the trio were UNHCR cardholders.
