Bouncers attack innocents

On Saturday the 29th November 2015 a group of us went to Chicago's Piano Bar on Beyers Naude drive. It was incredibly busy therefore due to this, while dancing, one of our friends bumped into another man. This man became aggressive and started to push and shove our friend. Once our friend pushed this man off of him and tried to walk away, the bouncers were called to kick us out. When trying to explain to the bouncers that we had done nothing wrong they became aggressive with us. Once by the stair case, the bouncers lifted one of our friends up and attempted to throw him over the balcony, another continuously punched our friend. In defense, our friends tried to fight the bouncers off of them, but then one of the bouncers pulled out pepper spray and sprayed them in the face. This caused immediate blindness, however the bouncers proceeded to abuse our friends. One of them was punched in the face, breaking his nose while he was helpless and could not see. Another bouncer pushed our friend down the stairs, he fell and lay there unconscious for some time. Another was punched in the ribs while trying to walk down the stairs blinded. This is completely unacceptable and charges will be laid
