Additional Sessions Judge Gulshan Kumar freed accused Geeta Arora alias Sonu Punjaban of the charges of MCOCA due to lack of evidence.
The court said that the police has failed to produce concrete evidence against the 33-year-old accused.
Delhi Police in April 2011 had slapped the stringent MCOCA on Punjaban for allegedly running an organised sex racket in the capital and nearby cities in 2011, besides being involved in a murder case.
Police had arrested Punjaban from south Delhi's Mehrauli area on April 1, 2011.
The police accordingly led a trap and deployed one of its officers as decoy customer and struck a deal with tout Raju Sharma and Punjaban for two girls for Rs 7,000 each.
