A former official with Barack Obama's U.S. Senate campaign has filed a federal lawsuit accusing Chicago police of improperly arresting him while investigating a sexual assault.
Craig Huffman was an assistant treasurer for Obama's 2004 campaign.
He was arrested in 2011 at his real-estate investment firm after a hostess from the Tavern on Rush restaurant chose his image from a photo lineup. Huffman was later acquitted.
Huffman was at the restaurant the night the hostess says someone groped her.
According to the Chicago Sun-Times, the suit accuses police of including his photo in the lineup even though he did not match a description of the suspect.
The city's Law Department said it had not seen the suit and could not comment. The restaurant owner's spokesman could not be reached.
