Here is a portion of the Chicago Tribune story:
Sherman Wilson, 55, of the 7400 block of North Ashland Avenue, brandished a silver knife on the Red Line headed toward Howard Street, demanding that a rider hand over his wallet, cellphone and watch, authorities said. Wilson struggled with the victim, pushing him to the ground and taking his watch, prosecutors said.
Wilson was arrested Thursday when a Chicago Transit Authority security guard recognized him from surveillance video of the Red Line attack, prosecutors said. Sherman was arrested at the Jarvis Avenue station in Rogers Park. Chicago Police Department News Affairs did not have information about when the robbery occurred.
Wilson was charged with felony armed robbery and is being held in lieu of $250,000 bond.
