(CBS/AP) LOS ANGELES - Police say none of those shot or arrested at a Halloween party on the campus of the University of Southern California late Wednesday were USC students or staff.
The shooting, apparently triggered by an argument between party crashers, critically injured one man, wounded three and triggered a campus-wide phone-email-text alert for students to shelter in place.
Around 11:30 p.m., two men were arguing outside the Ronald Tudor
Campus Center when one of them pulled a gun and opened fire, said USC police Capt. David Carlisle. One man was shot several times and critically wounded and three bystanders were wounded with non-life threatening injuries, he said.
About 10 minutes after the shooting, two men were arrested by campus police and turned over to Los Angeles police.
According to CBS Los Angeles, police are still investigating whether or not the second person in custody was involved.
Los Angeles Police Department Commander Bob Green said none of the victims or the suspected shooter are associated with USC, CBS Los Angeles reports.
"The shooting incident on UPC campus did not involve any faculty, staff or students of USC," the university reportedly said in a Trojan Alert.
The student alert was lifted about three hours later and students were advised a normal class schedule was planned Thursday.
Carlisle said about 100 people attended the student-only party, sponsored by a student group. Dozens more were outside.
"This is the first violent crime we've had on campus this year," Carlisle said.
In April, two USC graduate students from China were shot to death in a car about a mile from campus. Police believe Ming Qu and Ying Wu were victims of an apparent robbery.
Two men have pleaded not guilty to murder charges in the case. Trials are pending.
