Investigation papers on such cases to the deputy public prosecutor's office were
often returned marked "NFA" (no further action) for lack of evidence.
Selvakumar said police were working closely with the local authority on the
problem.
"Most of the time, there is insufficient evidence to prosecute those arrested,"
he said.
He added that some of the women had been deported but this had not curbed such
activities.
Selvakumar said police had recommended last year that the local council revoke
the licence of a restaurant in Jalan Kampung Selamat where the women gathered
for dinner every evening.
