A wireless transmitter, believed to be of Chinese origin, has been recovered in Himachal Pradesh's remote Kinnaur district, which shares a boundary with China, police said on Saturday.
"A VHS set in working condition was recovered from forests in Moorang area three days ago. We are investigating the case," police told IANS here.
He said the antenna of the set, whose solar charger has some Chinese inscriptions, was hinged to a tree.
Kinnaur Superintendent of Police Veena Bharti told IANS that the set was recovered on the basis of information provided by state forest officials.
"We are investigating the origin of the set. We have questioned locals. Some tourists may have used the transmitter for communication, but it's too preliminary to say anything right now," Bharti added.
Police said the area from where the set was found was within 10-15 km aerial distance from the China border.
"The set was recovered just 1 km ahead of the Indian army check post at Akpa," a police official said, who didn't wish to be identified.
In March last year, legislator Ram Lal Markandey had said in the state assembly that the Indo-Tibetan Border Police (ITBP) in Kaurik had spotted helicopters close to the international border in Spiti Valley.
At that time, Markandey had said the latest intrusion by China at Kaurik, some 330 km from Himachal Pradesh's capital Shimla, was the second of its kind in four months.
Himachal Pradesh shares a porous border with China and police say smuggling of rare species of fauna and Chinese goods like blankets and thermos flasks are quite frequent.
