Cell phone call leads to false alarm at school

More than 30 SWAT officers carrying guns swarmed a school in Winnetka after a district employee's cell phone mistakenly dialed his wife and she became frantic at hearing garbled, disturbing music.

Winnetka Police Chief Joseph De Lopez tells the Chicago Tribune that Monday's law enforcement response came because the unidentified employee's wife was the last number dialed on his cell phone. De Lopez says she believed "someone was holding him hostage."

School district interim co-superintendent Mark Friedman says the music had "gangster-like" lyrics.

Police were positioned at school entrances and interrupted a school board meeting. The middle school's 500 students had gone home for the day. Police gave an all-clear after about three hours when they found the employee safe at home.A
