Police said that K Rawngbawlliana, a constable in the Third battalion of the India Reserve battalion, posted at Nagaon shot himself with his Self-loading rifle reportedly due to family problems.
"He committed suicide after he learned that his wife in Aizawl deserted him for another man," the sources said, adding that his body would be taken to Mizoram-Myanmar border Champhai town where his funeral would be held tomorrow.
The Third IR battalion was deployed in Assam since January last year.
