The exhibition, which is titled "Borders" and is on loan from Icelandic artist Steinunn Thórarinsdóttir, comprises 26 life-size human sculptures in a garden named after Sir George Solti at East Jackson Drive and South Michigan Avenue.
The 13-year-old boy, whose name has not been released because he is a minor, has been cited in a juvenile petition with criminal defacement of property greater than $300, criminal damage to government property greater than $500 and less than $10,000, possession of paint or a marker with intent to deface and possession of spray can or a marker by an underage person.
Police found "numerous spray paint cans and permanent markers" belonging to the boy after taking him into custody, according to a news release announcing the charges Monday.
The president of the Grant Park Conservancy said this weekend that two signatures had been left on the tagged statues, but Monday's news release said the 13-year-old boy was "the offender" responsible and did not mention any other suspects.
