Allegations:
Martin was in her friend's parked car across the street from her South Chicago home when she saw a gray unmarked police car speeding north without its lights or sirens on. The car turned around and headed south, this time with its lights on, and parked next to the car Martin was in. When one officer got out and asked Martin to get out, she asked why and the officer cursed at her, pulled her out of the car and slammed her against it, then twisted her arm behind her back and slammed her against the car several more times. When she complained, the officer held her more tightly, handcuffed her and walked her over to the unmarked police car. The officers took the car keys from Martin's friend, handcuffed him and searched the car but found nothing illegal. Martin's friend was given a ticket for not having a Chicago car registration sticker. Police then drove the unmarked car around the neighborhood and discussed what to do with Martin. The officers threatened to take her to a police station before letting her go a block away from her home. Martin went to the hospital for medical treatment and was found to have a fractured clavicle.
