Two Cal State Fullerton students were stabbed near the Pi Kappa Phi Fraternity house on Sunday morning, according to the university’s police department.

The students were stabbed during an altercation with two possible attackers in an alley near 2117 Teri Place, close to the north side of campus, a news release from Cal State Fullerton University Police stated.

The victims, both identified only as male students, were believed to be in their late teens or early 20s, said university police Capt. Williams.

The fall semester begins on Monday and there were rowdy parties being thrown all weekend, witnesses told KTLA.

“Complete chaos, complete,” said one witness. “It was crazy with all the frat kids running through, frat kids parking their cars and running this way. It was crazy out here.”

It is not known if the victims are affiliated with Greek life and their identities have not yet been released. The attackers fled on foot after the stabbing, according to police.

“I just moved into this area and it’s already starting to want me to go. I’m not ready to be in any kind of danger in this area or what not,” said Anthony Kuehl, a neighbor.

Both students were treated and released with non-serious injuries, Williams said.

On Monday, the Fullerton Police Department said in a news release that one victim was stabbed in the chest and the other in the arm.

One attacker was described as 5-foot-10-inch, 170 pound white or Hispanic man in his early 20s, last seen wearing a light blue New York Yankees cap, black t-shirt and black pants. There is no current description of the other man.
