San Ysidro High School was placed on lockdown Wednesday as police searched for a suspect who stabbed a teen girl in a classroom, the San Diego Police Department said. After an hour-long lockdown and a campuswide search, police took a person of interest into custody at about 11 a.m. at an administ ration building on the campus at 5353 Airway Road, police said. The individual has not yet been identified. The stabbing was first reported just after 9 a.m. Police said a teen girl was stabbed “multiple times” inside a classroom by a male of unknown age who then took off, SDPD spokesperson Cesar Jimenez said. “There were some cameras that caught him and we’re following those leads of where he went to right now,” Jimenez said just before a media briefing ended abruptly as police patrol vehicles swarmed an administration building on campus. Shortly thereafter, police said a person of interest was in custody. Police previously reported the suspect was a male student, but later said that report was still under investigation. The exact identity of the suspect was not known. The teen girl, around 15 or 16 years old, was taken to the hospital, where she remained in unknown condition accompanied by law enforcement officers and school representatives, Jimenez said. Some witnesses told NBC 7 the stabbing occurred over a breakup, but police could not confirm those reports. What San Diego police could say was that they do not believe there is a threat to other students. To parents, Jimenez said, “We understand your concern. We do believe this an isolated incident. There are no other students who have been hurt.” Please refresh this page for updates on this story. Details may change as more information becomes available. ...read more read less
