Los Angeles students and teachers return to class for the new academic year Thursday under a cloud of apprehension after a summer filled with immigration raids and amid worries that schools could become a target in the Trump administration’s aggressive crackdown.

School officials say that the student, a 15-year-old boy, was detained in an "alleged case of mistaken identity."

The LAUSD is calling for limits on immigration enforcement operations near campuses after a teenage boy was detained by federal agents outside Arleta High School ahead of the new school year.
