In December 2010, the Essex County Prosecutor's Office formed a Cyber Crimes Unit to investigate child pornography, computer fraud and the use of the Internet and other technology in crimes. This unit is staffed by an Assistant Prosecutor, a Lieutenant of Detectives, and several Detectives.

Whether dealing with homicides, rapes, domestic violence, drug cases, online predators, child pornography or cyber stalking, technology is often the key to effective crime fighting in the 21st century. The Cyber Crimes Unit solves traditional crimes using computer forensics. The unit also educates members of the community on cyber bullying. Once limited to name-calling, today's bullying has morphed into cyber space and often involves much more complicated issues. The Internet Crime Complaint Center, a group that refers victims of cyber crimes to law enforcement agencies, reported that it received 14,520 complaints from New Jersey in 2009, up from 8,270 complaints in 2008.

The Cyber Crimes Unit works with local, state and federal law enforcement agencies. Many local police departments don't have the resources to investigate computer related matters and rely on the expertise of the Unit.
