Malaysian immigration authorities detained 123 migrant workers, including 45 Bangladeshi nationals, during an operation named 'Ops Mahir' at a plastic factory in Johor state. The raid, conducted on Saturday evening, followed weeks of surveillance and public complaints about illegal foreign labor employment. Johor Immigration Director Datuk Mohd Rusdi Mohd Darus said the detainees failed to produce valid work permits and were charged with violating the Immigration Act. The arrested workers include nationals from Bangladesh, Myanmar, Nepal, India, and Pakistan, aged between 20 and 48. One local human resources officer was also detained. During the operation, panic spread among workers, and several attempted to flee before officers sealed all exits. All detainees have been sent to the Setia Tropika Immigration Depot for further questioning, and authorities confirmed that legal proceedings are underway.
