An ambulance assistant of the Indian Army returning to duty from leave administered mouth-to-mouth resuscitation to an eight-month-old infant on a train and saved his life, a Defence official said on Saturday.

Sepoy Sunil, posted in a field hospital of the Army in the north-east, administered cardiopulmonary resuscitation (CPR) to the infant and stabilised the baby while travelling on the New Delhi-Dibrugarh Rajdhani Express, he said.
