Sunday is supposed to be their day-off but some Filipino maids have worked "overtime" to make extra income.

The maids were found to be working at night entertainment outlets in Kuala Lumpur as guests relations officers (GROs).

This was discovered by enforcement officers from the Immigration Department during a raid at a disco in Bukit Bintang on Sunday.

They arrested 13 Filipino GROs, aged between 30 and 40, and were shocked to find out these women had weekday jobs as domestic workers.

The women were among 47 people detained in a series of operations at entertainment outlets and massage centres in the city.

Also arrested were 32 China nationals including three men who worked at three massage parlours in Kepong.

The others picked up were a Bangladeshi waiter and a 30-year-old massage parlour operator.

The foreigners were being investigated for misusing the work permit and would be deported if found to have violated the work permit conditions.
