A rubber glove factory in Klang allegedly moved workers staying in dormitories to a nearby hotel and did a cleanup exercise the night before a raid by authorities on their premises.
Sources claimed that the manufacturer had been tipped off by "government insiders".
Human Resources Ministry deputy director-general (operations) Mohd Asri Abdul Sahab declined to comment on the alleged leak of information.
"From the aspect of our operations, we have done it properly. As for other issues (concerning the alleged leak of information), I have no comment," he told the media.
