Colon, 53, was stopped after his 2006 Honda was seen drifting between westbound lanes without signaling as he prepared to exit the highway, Bond said. After being given field sobriety tests, he was arrested and charged with DUI, driving on an expired license, improper lane use and failure to signal.



Bond declined to say whether Colon took a breathalyzer test, as police often do in such cases. The alderman is due in court on Aug. 15, she said.



Today the alderman, whose ward includes the Logan Square area, declined to comment, citing his attorney's advice.



"It really doesn't help me to talk about details of the case, because it's not something that needs to be tried in public," Colon said at City Hall. "I am cooperating, I have every confidence in the legal system that justice will be served in this matter, and I really want to just focus on just serving my constituents and representing my ward and its neighborhoods and not let this be a distraction. But it's not something I'm at liberty to talk in detail about."



During Colon's first successful run for alderman in 2003, his 1995 DUI conviction and subsequent citations for driving on a suspended license became a campaign issue.
