The army, however, said, that an officer was injured when a few soldiers became agitated and scuffled with seniors following the death.
The army said there was no “mutiny-like” situation.
“A case of death of a jawan during routine training activity has taken place in an infantry unit in the Northeast. It is not a case of any mutiny,” the army said in a statement.
It said the soldier complained of chest pain prior to a route march. He was checked by the medical officer and found fit. But the soldier collapsed during the training.
The army said four to five soldiers got emotional when they were being consoled by a senior and “indulged in agitated behaviour leading to minor scuffle”.
It said no one was injured seriously and the incident was being investigated.
