KUALA LUMPUR: The passages led to a nearby shopping complex and car park in the Bukit Bintang area.
They are secret routes for the karaoke’s guest relations officers and customers to flee in the event of a police raid.
Police discovered five passages on Saturday in a surprise check at the karaoke at 4am yesterday.
Some 400 workers and customers, aged between 25 and 45, were still at the karaoke enjoying the night although it was past the opening hours.
City Police anti-vice, gaming and secret society division chief Supt Zaki Masroh said nine men were detained – seven are believed to be connected to secret societies while two others are wanted by police for vehicle theft and cheating cases,” he said adding that the owner of the premises would be fined for operating beyond the permitted hours.
In a separate raid at a discotheque in Kuchai Lama, a city police narcotics team, led by Asst Supt Tan Kim Tong, checked 110 men and 66 women still in the premises at 3.30am.
