Taggers deface wall in exclusive neighborhood

It's nothing new for taggers to cover the walls of Chicago buildings with spray-painted graffiti. But they don't usually choose targets in one of the city's most expensive neighborhoods, and they don't usually keep their designs hidden with a tarp until they're completed.

Chicago police say some taggers, who left at least three signatures behind, scaled a cyclone fence early Monday morning to put 50 feet of spray-painted deigns on the rear brick wall of a coach house in the city's Gold Coast neighborhood on the Near North Side.

Officers say the street artists defaced the coach house behind the protective cover of a tarp and then tore it off when they left to unveil their work.

Builders have been working on the multimillion-dollar site for two years.
