CHICAGO, Illinois (CNN) -- Robin Petrovic, a college English teacher, was out dancing at a popular Chicago nightclub, the "Funky Buddha Lounge," when she got into an altercation with the bouncer and called police for help.
But according to Petrovic, the officer who showed up -- James Chevas, a 12-year veteran -- turned on her when she refused to sign a blank incident report and tried to write down his badge number.
"He picked me up and threw me face down into the ground. And since my hands were handcuffed behind my back, I couldn't break my fall at all, so I just landed on my face," she told CNN.
Petrovic is one of thousands of ordinary people who every year accuse Chicago police of abuse. Few complaints result in disciplinary action.
