Pic Shows: The security guard choked and attacked the young man outside the pub; This is the moment a young reveller is choked until he loses consciousness by an aggressive nightclub bouncer. Eyewitnesses with smartphones filmed the confrontation between Christian Esquivel, 22, and bouncers at a club in the Malvinas Argentinas area of the eastern Argentinian province of Buenos Aires. The footage shows Christian arguing with the doormen after he reportedly tried to leave the club with a bottle of vodka he had bought inside. After one bouncer slaps and roughly pushes him aside, Christian starts following the man and filming him with his smartphone. One of the bouncers then grabs the young man around the neck and chokes him until he loses consciousness. Christian then falls in a puddle on the wet ground where he is clearly out cold. His friends rush to his aid and eventually he comes around but he appears dazed and confused. Christian was later treated at a local hospital for injuries including a twisted shoulder and bruising to his face and body. The footage was posted online by an eyewitness and Christian took to social media where he said: "As I went through the exit, Marcelo Touron (my principal aggressor) took my bottle and pushed me." He said he asked the bouncer for his details so that he could report him, but he was then attacked by another doorman. The owners of the nightclub have reportedly issued an apology for the incident and said the bouncers involved in the incident had been sacked.
