If you want know the full story you have to watch the video taken by the officer at the check-in counter.
It was clearly shown that his check in baggage was more than 7 kg and he paid 1200/- rupees as penalty but the staff at thecounter failed to provide the receipt. He discarded his personal clothes in the dustbin to reduce the weight. Still all these incidents happened.How dare a civilian raised his hands and slapped an army officer when he was under the protection/custody of a CISF personnel?
