Los Angeles Unified School District leaders are calling for limits on immigration enforcement near campuses after a 15-year-old boy with disabilities was pulled from a car, handcuffed, and briefly detained outside Arleta High School on Monday in what officials describe as a case of mistaken identity. The incident happened around 9:30 a.m. on Monday, just days before more than half a million LAUSD students return to classrooms. According to Superintendent Alberto Carvalho, the student " who attends San Fernando High School " had gone to Arleta High with his grandmother to accompany a relative registering for classes.
