Los Angeles police arrested a 21-year-old university student in connection with an online threat to shoot people on campus, officials said Saturday. Police arrested Carlos Huerta, a senior at Loyola Marymount University, on suspicion of making criminal threats. Huerta was taken into custody on Saturday night near his apartment on campus. Huerta is suspected of posting a message that he would shoot and kill as many people as possible on campus before being killed himself by police, authorities said. The anonymous threat appeared on a blog called Juicycampus.com, used primarily by college students. University officials reported the threat to police on Saturday, said Los Angeles Police Department spokesman Officer Mike Lopez. Calls made to Loyola were not immediately returned.
