Seven Vietnamese men, all of whom were naked, were arrested during a raid at a massage parlour in Perai Jaya, Butterworth yesterday.

Penang Immigration assistant director Abdul Rahman Hassan said in the 4.30pm raid, the seven, aged from 20 to 33 years, were "servicing" local men.

"All, the masseurs and the clients were naked," he said when contacted.

He said the seven Vietnamese men were held because they had violated their social visit passes and were working without permits.

The clients were also held to assist investigations, he added.
