Inhuman-unruly Indigo air staff

The complaints on Indigo Air staff are going up. Here in the video attached below, we can see the ground staff fighting with a passenger and pressing his neck while he is shouting for help. He was abused and prevented from boarding the bus. The video shows that the passenger was assaulted in the airport openly in front of other passengers.

Many complaints were being registered again Indigo but no action so far. There were times when passengers also did some hungama against the staff.
