Officer John McCarthy told the Chicago Tribune that he and his partner cornered a robbery suspect just minutes after a man help up the Fifth Third Bank in Old Town on Monday.
The officers found cash on the man and brought him back to the bank where he was immediately identified as the robber.
McCarthy said the robber picked a "bad time" to hold up a bank given the heavy police presence on Chicago streets for the NATO summit.
"It was just poor planning on his part," McCarthy said.
