James Ramhmingthanga, a constable posted in the Mizoram-Tripura border town of Kanhmun, had come riding a motorcycle to Aizawl on an assignment on Saturday.
He had reported at the Vaivakawn police station and returned on Sunday morning. He called his wife along the way from a village called Dampui, which borders a thick forest through which the lone road, a winding route perched on the mountain-side, that connects Mamit with Aizawl passes.
But James never reached home.
The Mamit district police, rescue teams and close to a thousand Young Mizo Association volunteers from at least three towns and villages took part in the search operation that began Sunday night.
Mamit district Addl SP Lalchunglura said there have been no trace of the constable nor of the motorcycle and no leads have as yet been found.
