The suspects were picked up to facilitate investigations into the alleged offence at a fertiliser store in Kampung Palas.
Sarawak CID chief Dev Kumar MM Sree Shunmugam said the suspects were picked up following a report lodged at the Limbang police station by the victim’s 32-year-old mother.
In a statement here, he said the woman who worked as a plantation worker told police she stumbled upon her daughter lying semi-nude on a mattress after the girl was spotted playing with the two boys.
