CPD Blue is looking for an individual who climbed a city water tower at Atlas Road & Industrial Avenue in Coeur d'Alene and left behind graffiti. A work crew cleaning the tower Monday discovered the graffiti left behind on top, 157 feet from the ground, according to Water Department director Jim Markley. The tower was last cleaned a year ago. The city will install a device to prevent anyone that isn't a city worker from climbing the tower, Markely said.
