Report Suspicious Activity Your early involvement and open communication can prevent your child from becoming a victim of a predator. Report suspicious online activity when something does not feel right to you or your child. Trust your intuition! If you suspect someone is attempting to entice your child online, do not delete any material, and do not shut down the computer. Immediately contact your local law enforcement agency and make a report to the National Center for Missing & Exploited Children (NCMEC) at www.cybertipline.com or call 1-800-THE-LOST.
