A Streamwood police officer accused of being a man with his baton earlier this year has been fired.
Mandarino last month was indicted with three counts each of aggravated battery and official misconduct.
Video from his squad car's dashboard camera appears to show him beating Ronald Bell, despite the fact that Bell appeared to be complying with Mandarino's orders.
Bell needed seven stiches to close a gash in his ear, had multiple bruses and was treated for a concussion. His friend, Nolan Stalbaum, twice was met with Mandarino's stun gun when he exited the car.
Bell has filed a federal lawsuit against Mandarino and the village of Streamwood.
The Chicago Tribune reported that Mandarino can appeal his firing.
