The sculptor of Wall Street’s “Charging Bull” statue is accusing New York City of violating his legal rights by allowing the “Fearless Girl” statue to be installed facing the bronze beast, without his permission.

Attorney Norman Siegel told The Associated Press that Arturo Di Modica will explain at a news conference Wednesday exactly how he’s challenging city officials who issued a permit for the bronze girl to stay until February. Siegel said he’s demanding that the city release documents showing what procedures were followed.
