The State Immigration Department of Malaysia rounded up 80 illegal immigrants including 65 Bangladeshis  during 'Ops Mega' at a construction site in Kampung Raja in Besut of Malaysia on Thursday, reports New Straits Times.

Its director Wan Suhaini Wan Mohammad said a team of 15 enforcement officers led by its chief Mohd Muda, and four officers from the Registration Department raided the site at 11.30am. The raid ended at 3 pm. Suhaini said her personnel checked 145 foreign workers and 80 of them were nabbed for not having necessary legal documents and permits.

"65 Bangladeshis, Three Myammars, five Chinese and seven Pakistanis were rounded up under Section 6(1)(c), Section 15(1)(c) and Rule 39(b) of the Immigration Act 1959/63," she said yesterday.

"They did not possess valid travel documents, had over stayed and violated their social visit passes," she said, adding that a local man was summoned for harbouring the detainees.

Suhaini said all the detainees, aged between 18 and 53, were sent to the Ajil Detention Centre for further investigation.
