India's triumphant Olympic contingent, including history-making javelin throw gold-medallist Neeraj Chopra, returned to the country on Monday and was greeted by frenzy and chaos at the airport where supporters jostled to catch a glimpse of their new sporting heroes. The athletes were welcomed by a Sports Authority of India (SAI) delegation headed by its Director General Sandeep Pradhan, who was accompanied by Athletics Federation of India head Adille Sumariwala.
