A massive search operation was undertaken after the chopper with Tirap Deputy Commissioner Kamlesh Kumar Joshi and captains M S Brar and Rajeev Hoskote on board went missing after take-off from Khonsa in Tirap district of Arunachal Pradesh on August 4.
The chopper was found yesterday between Thinsa and Sanglian villages in Tirap district of Arunachal Pradesh but the fate of the three occupants is not known.
"We are yet to reach the base of the gorge where the chopper is suspected to have crashed," Civil Aviation secretary B M Mishra told PTI.
Attempts are on to drop down from air to the deep gorge where the main body of the chopper is sighted. The ground team is also working hard to approach the bottom of the gorge, Mishra said.
The search operation will continue tomorrow morning.
