A man was taken into custody after trying to rob an off-duty Chicago police officer at knifepoint early this morning.
About 12:30 a.m., the 20-year-old man bicycled toward the officer as he was walking in the 1700 block of West Diversey Parkway. Displaying a knife, the suspect announced a robbery.
The off-duty officer announced his office and took his assailant into custody "without incident".
Police officers patrolling the area responded to help the officer and took the suspect to the Town Hall District station for processing.
