Chicago Police Brutality? Brothers Allege They Were Mistaken For Robbers, Beaten By Cops (VIDEO)

Fox Chicago News has obtained a security video which two brothers allege shows Chicago Police beating them, having mistaken them for robbers as they closed up a food and liquor store where one of them worked.

Michael Ayala, 23, told Fox that he saw several CPD officers "roughing up" his brother Adrian Ayala, 18, while he waited outside the shop. Michael Ayala claims that after the police released them without issuing any charges, he informed the officers that the incident had been caught on the stores security cameras and he "wasn't going to let it go." It was then, he alleges, that the police "bum-rushed" him and his brother, captured in the security video below.
