A high-profile sex racket was busted here on Saturday with the arrest of five call girls and their pimp, police said.
The racket was being run in Lucknow's Madion area. Many girls and clients were caught in the act during the raid, police said.
Officials said it could be possible due to residents' tip off, as people in the neighbourhood turned suspicious about the ongoing activities late at night.
Hundreds of DVDs, liquor bottles, addresses, visiting cards and other objectionable items were seized from the house.
