CHICAGO (AP) — Two men who were arrested as teenagers and spent nearly half their lives behind bars after being wrongfully convicted of murder have sued Chicago police and Cook County prosecutors.

John Fulton and Anthony Mitchell last year were exonerated of the 2003 murder of Christopher Collazo. The federal lawsuit filed Wednesday by Fulton and Mitchell accuses police of manipulating photo evidence, abuse and fabrication of their alleged confession.

It seeks damages for civil rights violations and malicious prosecution. Spokesmen for Chicago police and the Cook County state’s attorney’s office declined to comment on the lawsuit.
