Malaysian authorities have rounded up over 3,100 foreigners this month as part of a major crackdown on illegal immigration.
The crackdown began July 1, the day after the deadline for all undocumented foreign workers to register with the government. The latest arrests occurred early Wednesday, when police arrested dozens of workers at a construction site in the coastal town of Port Dickson.
Authorities are targeting undocumented migrants who have traveled to Malaysia from neighboring countries such as Indonesia, Bangladesh and India, to work construction jobs and one of the country's many plantations.
More than 60 employers who allegedly hired foreign workers have also been arrested in the crackdown.
