ITHACA, N.Y. (AP) — A national fraternity says it will close its Cornell University chapter in the wake of an ongoing investigation into an attack against a black student that police say may have been racially motivated.

Cornell University officials say Psi Upsilon's alumni board of governors has told the Ivy League school that it planned to immediately close the chapter. Cornell banned the chapter last year for violating the university's code of conduct.

The New York Times reports that students who may have been involved in the frat were accused of attacking a black student last Friday. Ithaca police say the student was beaten and called a racial epithet.

Police say they've charged 19-year-old John Greenwood with assault. University officials say he's a Cornell student.

His lawyer, Raymond Schlather, told the Times his client wasn't involved in the assault.
