MALACCA - The Immigration Department has detained 29 Vietnamese women who worked as guest relations officers (GROs) during a raid at two condominium units in Klebang Kecil near here.
Fifteen officers raided the units at about 12.30pm on Wednesday, catching the women - aged between 18 and 55 - by surprise.
Nineteen had misused their social visit passes while eight others did not have permit to stay in the country.
The two other women had overstayed.
The eldest among them is believed to be the "mummy".
Following a tip-off, the officers had kept watch on the premises for two weeks before moving in.
"We had to force open the doors when our knocks were not answered," state Immigration director Kamalludin Ismail said in Ayer Keroh on Wednesday.
Initial investigations revealed that the women worked at entertainment centres in the city.
