To report a crime in New Jersey, contact your local police department or the state police, advises the New Jersey State Police. In an emergency, dial 911 for the police, fire department or an ambulance. For non-emergencies, the contact method varies depending on where the crime occurred.
Report crimes to the police department in the city where the crime occurred. You can visit the police station or call it to report the crime. Each police station lists its phone number on its website. Some police departments also allow you to report crimes online. To do so, input the necessary information on the department's website, and wait for an officer to contact you after receiving the information, explains the Newark Police Department.
To submit a confidential crime tip, you can do so online, by mail or by phone, according to the New Jersey Division of Criminal Justice. The online form is available on the Division of Criminal Justice section of NJ.gov, as of 2015. The form page also provides a phone number and a link for obtaining the division's mailing address.
To report a crime to the New Jersey State Police, contact the state police by phone, or visit one of the troop locations. Although the New Jersey State Police allows email contacts as well, the organization advises against reporting crimes that way.
