Receiving Email or Text Alerts About Crime in Your Neighborhood

Citizen Observer is a service used by the Cambridge Police Department to send e-mail and text alerts about crime and other notifications to the various neighborhoods of the City.

Registering for Citizen Observer

Residents are encouraged to sign up to receive notifications for their neighborhood as well as the "CITYWIDE" group.  The groups are:

  • Cambridge PD: CITYWIDE

Notifications will come in three forms:

  1. Citizen Alerts - The most important and timely notification from the police will be labeled as such and sent to the affected neighborhood(s) and the "CITYWIDE" group.  These alerts will typically be sent within 12 hours of the incident during the following scenarios:
    • Threats to Public Safety
    • High Profile Incidents
  2. Advisory - This type of notification will be primarily used to share important information with the community and will be sent to affected neighborhood(s) and the "CITYWIDE" group if the information affects the entire community.  Typically, these notifications will be sent following the monthly BridgeStat release, and will include information about the following:
    • Significant Incidents and Follow-ups
    • Crime Patterns Identified in BridgeStat
  3. Neighborhood Info - Notifications will be sent to inform individual neighborhoods about neighborhood-specific information that does not apply to the city as a whole, such as:
    • Neighborhood Meetings
    • Other Neighborhood-Specific Announcements
Citizen Observer also allows people to text anonymous crime tips to the police, helping provide valuable information to investigators and make our community a safer place.

Annual Crime Reports

The Cambridge Police Department’s Annual Crime Reports, produced by the Crime Analysis Unit, are an attempt to provide detailed information so that citizens can make informed decisions about crime and safety in their neighborhoods. The more information made available to the public, the better the input will be in aiding the Police response to crime.

The goal of our Annual Reports is to provide this partnership with the knowledge to ensure the desired quality of life in all the neighborhoods of the City.  For older reports, including quarterly crime reports and monthly BridgeStat releases, please visit our Publications page.

Monthly BridgeStat Reports

The Cambridge Police Department produces a monthly public report (called BridgeStat) to the community on current police priorities in terms of crime, traffic, community concerns, and disorder issues in the city. This is made available on the Cambridge Police Department’s website at on the first Friday of each month.

BridgeStat is a multi-layered, dynamic, intelligence-based approach to crime reduction, quality of life improvement, and personnel and resource management based on four distinct principles – accurate and timely intelligence, effective tactics, rapid deployment, and relentless follow-up and assessment. At the core of our approach is a philosophy that fosters teamwork and creative problem solving. Police personnel hold bi-weekly meetings to devise strategies and tactics to solve problems, reduce crime, and ultimately improve quality of life in our community.

Filing a Motor Vehicle Crash Report

File an Accident ReportM.G.L. Chapter 90, Section 26 requires a person who was operating a motor vehicle involved in a crash in which (i) any person was killed or (ii) injured or (iii) in which there was damage in excess of $1,000 to any one vehicle or other property, to complete and file a Crash Operator Report with the Registrar within five (5) days after such crash (unless the person is physically incapable of doing so due to incapacity). The person completing the report must also send a copy of the report to the police department having jurisdiction on the way where the crash occurred. If the operator is incapacitated but is not the vehicle's owner, the owner is required to file the crash report within the five (5) days based on his/her knowledge and information obtained about the crash. The Registrar may require the owner or operator to supplement the report and he/she can revoke or suspend the license of any person violating any provision of this legal requirement. A police department is required to accept a report filed by an owner or operator whose vehicle has been damaged in a crash in which another person unlawfully left the scene even if damage to the vehicle does not exceed $1,000.

You may download and fill out a Motor Vehicle Crash Operator Report from the Massachusetts RMV.
