North Carolina State University announced an immediate halt to all fraternity activities involving alcohol Friday, less than 24 hours after campus officials obtained a copy of a “pledge book” filled with jokes about sexual assault and lynching black men.

The Pi Kappa Phi fraternity was suspended Thursday night, after a student showed the book to the staff of WRAL, a Raleigh television station.

“It will be short and painful, just like when I rape you,” read one statement in the book, according to the WRAL report.

“That tree is so perfect for lynching,” reads another.

On Friday afternoon, the campus announced a “temporary cessation of all social activities including alcohol” for the school’s fraternal organizations.

“This is about working with the Greek community to agree on shared values and to exceed the behavioral standards,” Mike Mullen, vice chancellor for academic and student affairs at the university, said in a statement.

The school will hold a series of meetings with the campus’ Greek leadership to identify ways to improve diversity and identify other issues that need to be addressed, according to the statement.

The Pi Kappa Phi controversy marks the second time NC State has had to suspend a fraternity this month. Campus officials suspended the Alpha Tau Omega fraternity’s local chapter on March 1, after a student made a sexual assault complaint involving some of its members
