Cops Use Facebook To Bust Post-Prom Party

Police in northern New Jersey infiltrated Facebook to learn that students were planning to bring alcohol and drugs to an after-prom party.

Police created fake identities to enter the social networking site and found what Fair Lawn High School students were going.

Officers stopped the caravan a few miles from the high school and arrested four 17-year-old boys who officers say were carrying marijuana, scales and baggies commonly used to package the drug.

School Superintendent Bruce Watson says the district doesn't check Facebook on a regular basis unless there's a reason. Watson says the district generally leaves Internet patrolling to police.

Police Sgt. Derek Bastinck says teenagers are cavalier about accepting people into their network of friends.
