The student said she had attended a party at the Kappa Sigma fraternity, where she was attacked by a man she did not know in the early morning hours Sunday, Cal State Long Beach police stated in the bulletin issued Monday.

The attacker was described only as a Hispanic man in his 20s, according to the bulletin.

Both students and non-students may have attended the party, in which alcoholic beverages were being widely consumed, according to the bulletin.

The Long Beach Police Department was investigating the case, but a spokeswoman for the department said it was believed to be an isolated incident and there was no threat to the public.

The Long Beach State Kappa Sigma chapter was suspended by the fraternity’s leadership, based in Virginia, according to a university spokesman.

The fraternity issued a statement, saying it was “made aware of allegations made against an individual” at the Cal State Long Beach Theta-Beta Chapter.

“The Fraternity has suspended the operations of the Chapter while it conducts a full investigation of the events surrounding the incident,” the statement read.

Anyone with information was asked to contact the Police Department at 562-570-7368 or the department’s sex crime tip line at 562-570-7878.
