'Two Chinese helicopters entered India in August'

(Hindustan Times) : Two Chinese helicopters, along with seven to eight troopers on board, flew into Indian territory along the Line of actual Control (LAC) in Chumur area of Ladakh region of Jammu and Kashmir last month and damaged “unused bunkers” of India, before flying back undetected and unchallenged.
This has been stated in a report sent by Leh district administration to the state government, highlighting the point that while the Indo-Tibetan Border Police (ITBP) deployed in the area has sent the report of this incident to the ministry of home affairs, local administration was kept in dark, official sources told Hindustan Times. Deputy Commissioner, Leh, T Angchuk, when contacted, confirmed that he has “sent a report (about the incident) to the state government, and also deputed sub divisional magistrate  and station house officer of Nyoma ( under the jurisdiction of whom Chumur area falls) to visit the spot  to verify the facts and file a report.”
The Leh district administration came to know about this incident on September 9 and the SDM was deputed on a “fact finding mission” on September 11, sources in the state government told Hindustan Times. They were awaiting for an on the spot report of the SDM and SHO.
But the Indian army denied that any such incident has taken place. “No incident like this has happened,” Northern Command spokesperson Lt. Col Rajesh Kalia told Hindustan Times when asked about the army’s version on the reported incident.
Official sources, however, maintained that the two choppers with seven to eight Chinese soldiers landed in Chumur area, about 200 to 300  feet inside the LC on August 25th. They were there for 20 to 25 minutes. They wrote something in Chinese and also damaged the “unused Indian bunkers.”
The details, how they damaged the bunkers, are not known.
The ITBP personnel, who were at a long distance, however, could not react because of the distance and they are reported to have watched the incident, with the help of binoculars.
The ITBP’s DIG based in Leh, according to sources, has sent the report to MHA.
Ladakh has a 646 km long LAC with China. The LAC remains undemarcated at several places.
The Indian army’s stated position, often articulated by the top commanders is that “these are not incursions but transgressions which take place because of the varying perceptions of LAC.”
