Arizona State University police say a graduate student fatally shot himself in a professor's office.

ASU police commander James Hardina says the shooting occurred about 11:40 a.m. Monday.

Police say the student was apparently talking with a professor when he pulled out a gun and shot himself once in the architecture Design South Building on ASU's main campus in Tempe.

The name of the student has not been released.

Hardina says there is no further threat to ASU students or faculty.

ASU officials say the school is offering counseling services for those who may have known the student.

ASU spokeswoman Julie Newberg says the Design South Building is closed until further notice.
