TAPLEJUNG, January 1

The whereabouts of a man and his son, who have been stuck in an avalanche at Mikkakhola Rural Municipality-5 in Taplejung district, is still unknown.

A private helicopter deployed for their search returned after failure to find them. It made the search two times on Saturday.

The missing persons-Lakpatasi Sherpa, 55, and his 15-year-old son Pasang-have been stuck in the avalanche that occurred when they were shifting sheep shed, said the police.

However, phone conversations with the missing father and son have been established, he said, adding that during the phone conversation, they informed that they were taking shelter in a cave.

The local people are helping in the further search as well.

It was difficult to search for the missing persons due to bad weather, said the ward chair Dandu Sherpa. The helicopter will be sent again for the search, he said.
