CHICAGO -- Ben Baker, freed from prison back in January with all charges dropped against him, is suing the city of Chicago.
He claims former Police Sergeant Ronald Watts and several other officers framed him on false drug charges during an arrest in 2005.
After he refused to pay a bribe, Baker says, police planted drugs on him.
Baker's attorneys say FBI documents show authorities at the time were aware of allegations that Watts and his tactical team were involved in a criminal enterprise targeting residents in the Ida B. Wells homes.
Baker has filed a federal lawsuit against the city of Chicago, Watts, several other officers as well as former Police Superintendent Phil Cline.
Baker says this lawsuit is about getting justice for his family and exposing the police code of silence.
Watts and another officer named in the suit were later convicted and two police officers who blew the whistle on the crew faced professional retaliation.
Earlier this year, they settled for 2 million dollars with the city on the eve of a trial that would have focused on the police code of silence.
Police or the city's law department have not commented on the suit.
