Prostitution in the massage centres was exposed in a joint operation by cops and TV9. The cops took organisers of massage centres and women involved in the prostitution. According to police officials, massage centres are coming up in commercial complexes across the city without seeking permission from the GHMC. Massage centres are hiring women from other states and luring youth into sex by calling them. Organisers of massage centres are using ‘Just Dial’ directory to call customers for offering their services.
