Malaysian Immigration Department arrested 309 undocumented migrants, including 102 Bangladeshi, during an integrated operation carried out at a settlement near a construction site in Dengkil early today.
Among other arrestees, 193 are from Indonesia, eight from Myanmar, four from Vietnam and two from India, according to Malaysia's national news agency Bernama.
Those detained comprised 280 men and 29 women, aged 20s to 50s, the agency said.
Immigration director-general Datuk Khairul Dzaimee Daud said his department had received information from members of the public who claimed that there were individuals at the settlement who were believed to have violated the standard operating procedures (SOPs) of the movement control order.
He said, as a result, the department had raided the area and found that they did not comply with the MCO SOPs as prescribed.
"I arrived with the operations team and found that their settlement was so dense, dirty and did not have a proper drainage system, apart from having a place to gather and eat in large numbers.
"They also admitted that they lived in a group in one room, which is about four to seven people," he told reporters at the scene.
Khairul Dzaimee said this showed that they were free to do anything at the construction site without any compliance with the MCO SOPs.
He said this was the main purpose of the Home Ministry which directed the Immigration Department to help reduce positive cases of the Covid-19 outbreak at the workplace comprising immigrants.
He also explained how Indonesian women sneaked into the country.
"Indonesian women enter Malaysia using a social visit pass and continue to reside in the country beyond the stipulated time. In addition, they will live with their husbands who work illegally in the country.
"All these undocumented migrants will undergo the Covid-19 screening test on Monday to be carried out by the Putrajaya and Seremban district health offices," he said.
Khairul Dzaimee said after the screening test, these migrants would be placed at the Semenyih Immigration Depot to be detained and investigated in accordance with laws, before deportation.
During the operation, the Immigration Department also inspected 10 Rohingya refugees who are United Nations High Commissioner for Refugees (UNHCR) cardholders.
"Out of 10 UNCHR cardholders, only two of them were arrested for possessing fake UNCHR cards while the others were released," he said.
This integrated operation which started at 12:30am and went on till 2:30am was joined by 189 personnel members from various enforcement agencies including the General Operations Force, National Registration Department, Labour Department and the Civil Defence Force.
