The herd of wild elephants had come down from hills of neighbouring Bhutan in search of food and was creating havoc in the area for the last one week.
An elephant strayed from the herd and entered Natun Khunti village under Nagrijuli police station. It razed a house to the ground and trampled its owners to death.
The couple have been identified as Mahipal Barman and Swarna Barman.
