Nepal consulate sources told PTI that inclement weather hampered search operation and they have no news of Gayen and the accompanying two sherpas after they were caught in an avalanche on Tuesday.
They were trying to climb the 8,505-metre-high Yalung Kang, the second highest peak in the Kanchenjunga massif, also known as Kanchenjunga West.
The Himalayan Mountaineering Institute in Darjeeling has also sent their mountaineering instructor Tushar Kanti to coordinate the rescue operation from the base camp.
The state youth services ministry has sent a three-member team, including two mountaineers Ujjal Roy and Devdas Nandi, to coordinate the rescue operation from the base camp.
The mountaineer's family members have complained to West Bengal Chief Minister Mamata Banerjee that they are disappointed after learning that Gayen was "not on good terms with the search committee members".
Her brother Jyotirmoy Gayen, told reporters, "We want the Centre to intervene immediately and conduct the search".
While others decided to return to the base camp after summiting, Gayen along with two sherpas Dawa Wangchu Mingma Temba stayed back to conquer the Yalung Kang peak.
