UNC-Chapel Hill campus police found red paint on the Bell Tower bricks and a column of the Old Well, two of Chapel Hill's landmarks.

Police don't know who did it, but they found white-chalk graffiti referencing the college basketball rivals. Police spokesman Randy Young declined to describe the statements further. Police also found a cup with red paint residue inside.

Police think the incidents occurred about 3 a.m. Wednesday. The Old Well was being repainted by 8 a.m. The Bell Tower was cleaned up by the afternoon.

The vandalism took place on the eve of UNC-CH's ACC basketball showdown with N.C. State University. The Heels played the Wolfpack Wednesday night at the RBC Center in Raleigh.

The incident reminded Young of a similar act that occurred before the UNC-CH/NCSU game in 2005. In that incident, Young said, he thinks police caught the vandals in the act of stenciling an NCSU logo onto the bricks.

The Old Well once served as the only source of water for the Old East and Old West dorms at the heart of campus. It took its present design in 1897 under the leadership of President Edwin Alderman.

The Morehead-Patterson Bell Tower was dedicated in 1931. Alumnus John Motley Morehead originally wanted the bell to top the Wilson Library, but university librarian Louis Round Wilson wanted a dome.

Legend says that Morehead had the pointed tower built behind the library to look like a dunce cap on top of the dome.
