"We have recently filed report before Goa Children's Court seeking to close the case due to lack of evidence," Panaji Police inspector Siddhanth Shirodkar said today.
Singh was arrested along with five others in August 2013, after police raided a dance party in Panaji. Six girls was rescued during the raid.
All the arrested accused were booked under Prevention of Immoral Trafficking Act and later they got bail.
Singh had denied his involvement in the offence, claiming that he was called by his friend for a birthday party and he had arrived a little before police raided the place.
