NEW YORK, NY April 26, 2006 —The city's police department has begun sending mobile metal detectors to public schools that don't have permanent scanners at their entrances. The Acorn High School for Social Justice in Brooklyn was the first school chosen for the new crime-fighting program.

REPORTER: Schools Chancellor Joel Klein says there were no significant delays for students, and the scanning did yield results.

KLEIN: They confiscated one box cutter and they found a knife in a trashcan and they found one student who ran away, apparently had some marijuana on the student.

REPORTER: Police also found over 100 cell phones and several MP3 players, which are not allowed in schools. Those items were temporarily confiscated and then returned to the students.
