CHICAGO (AP) - Police say a suspicious package that forced the evacuation of Chicago's Millennium Park did not contain explosives and was left there by people participating in a "role-playing event."
The police department issued a statement late Saturday saying the package contained two bricks and that detectives are questioning three people in relation to the incident.
Police were told of the package at about 5:30 p.m. on Saturday and emptied the crowded park while officers inspected it.
Officer Darryl Baety, a police spokesman, says the package was wrapped in duct tape and had wires sticking out of it. It was left near the Cloud Gate sculpture, which looks like a giant metallic bean and is one of the park's biggest attractions.
