Chicago police question two men for cartoon publicity ploy

CHICAGO -- Chicago police say they questioned two men who posted 20 electronic advertising devices around Chicago as part of a nationwide publicity ploy for a cartoon show.

A police official says the two men haven't been charged. They were both released after questioning.

The signs were recovered yesterday from locations around Chicago, including trains, elevated platforms and storefronts.

The discovery of similar devices in Boston sparked terrorism concerns when they were mistaken for possible bombs.

Chicago authorities say the men who posted the devices were hired by a marketing company and told investigators they were instructed to place them at least ten feet high.
