University Of Kentucky Police Investigating Signs That Call Obama Racial Epithet

LEXINGTON, Ky. -- Campus police at the University of Kentucky are investigating two incidents in which a sign was hung that used a racial slur to refer to President Barack Obama.

University of Kentucky spokesman Jay Blanton says a professor found the first one on March 15 hanging on a door to the UK School of Law and turned it in.

A law student found another sign Thursday on a bus shelter.

Blanton says campus police could charge whoever posted the signs with third-degree criminal mischief. He says it's not clear whether anyone from the school is involved, but campus police are investigating because the first sign was on university property.
